Evolution, or am I just growing old?

I am a patient person and seldom lose my cool. Few people have seen the wrath of my anger, and I can easily count these incidents on one hand. This of course excludes my dear parents, in front of whom I have always aired and argued my point, often snubbing them. [what a mean thing to do nah!]
One incident I distinctly remember was during the rehearsals for a fashion show [yep! me being part of a fashion show would seem pretty far-fetched when you see me now...]. Anyways, so it was the first day of our rehearsals, a lazy Sunday afternoon. Some people had taken charge and I was happy to follow their instructions [never been a leader as such]. It was slow and dreary, but when you let yourself be led, you better respect the leaders. Now one smartass decided to break that golden rule and tell the self-appointed choreographer that it was all wrong. The 3 hours of sequence drawn and practised was not working out! There was a murmur amongst everyone saying 'yah, she's right'. But my stream of patience had run dry [maybe I was just thirsty] and I blew my top on that whistleblower. I shot back at her--

Why hadn't you spoken up before if you thought that the sequence was all
wrong? If it is all going haywire, you become the choreographer!

This shut her up for good. Any surprises if I told you she also dropped out of the fashion show, and the show did go on. So fabulously well that our team also won 'Best Choreography' award.
Coming back to the point...
Today, in the groove of a heated debate during a workhop at office, I found myself at loggerheads with the HR person. As such they are not a breed much-liked by me, and as much as possible I let them do the talking and carry on with their aggressive tactics to run me down. But not this time. I stuck to my side of the argument and pointed out the relevant justifications in the case study we were discussing. Don't know if they agreed with me, but decided to make me the spokesperson for the team. And I fought and scratched out at the other teams and their arguments, while possessively defending my own ground. Felt good to finally vent out my thoughts, after 5 days of listening to lecture on how the theory would better our lives at work.
Later in the evening, I met with friends at the club and we chatted about till around 10.30pm [quite late by B'lore standards]. When we got out I spotted an auto and asked him if he would take me to my destination. He agreed and quoted Rs 80. I asked him to charge 1 1/2 times the metre, which is the norm after 9pm, but he argued that it would amount to the same thing. I didn't pursue the argument further and quietly sat. When I reached home, I handed him a 100 buck note. Turning his head, he started to put his autorickshaw in gear. I politely asked him to return Rs 20 back. He claimed he had quoted Rs 100. This really got my temper boiling. I started to scream and argue and when he refused to return the money, I plonked myself into the auto and told him that I would not get out till he returned the money. Conveniently, he started blabbering in Kannada and using abusive language [I'm guessing], since a gentleman stopped his bike and came to the auto and started arguing with the driver. I managed to extract Rs 10, and that sort of simmered my anger and I walked off towards my residence. It was then I noticed that neighbours were peeping out from their houses to see what the hubbabaloo was about. I sneaked a look at my watch. It was 11pm! Not until now had I noticed the dead silence of the night. The act of putting myself into that auto and letting the driver take off where he pleased had been a stupid act of anger, and I am glad someone had timely intervened. I huffed and I puffed, and sulkily went to my house and stayed holed up there for the next 2 days.
