I got caught talking to myself at night by my neighbour.
So I have this habit of going to the roof of my house and just walk around talking to myself. I don't know why but this really helps me clear my head and make rational decisions and I sure as hell can't do this in my room or any other place in my house without being heard. The night air and some amount of solitude makes 100 times better.
There's also a swing there so I also use it to clear my head.
Anyway my house is also joined to another house (I can go to the roof of that house easily if try without jumping).
I always look around to make sure that no one is around so I can just stay in peace and I did that day as well.
There were no people and I really needed to get some things out of my chest so I began to rant to the air. I was also making intense hand signs (the ones you make unconsciously while talking) and well in the middle of that a granma who lives in that house came to the roof (of her house) to do something (I don't really remember what she did maybe to pick up some cloths).
And I didn't notice her as I was too busy ranting to myself then after who knows how long of her being there she knowingly coughed (kind of cough you give instead of saying "I am right here dumbass") and after hearing that I saw that she was there doing something my socially awkward ass hid myself behind this structure that was there and waited for her to go away (as I was not done ranting to the air).
I guess after 5 minutes I gave up, took my awkward ass downstairs and she probably noticed that I was hiding instead of going downstairs for 5 minutes (I know it doesn't sound long but well trust me it felt like the (one of the) longest 5 minutes of my life.
