My little brother is an ISTP. The older we get, the more serious he gets and the more I like to annoy him. He also often calls me crazy. The funny part is that he acknowledges that I am smarter than him, but act way more childish, and it goes on his nerves. We often discuss who is better where and to be honest, he has more strength than me, despite being two years younger. We agreed that I am the brain and he’s the arms. I also noted that sometimes he is colder than me, but loses his temper way faster. If we go in a argument he often starts to get violent, because I know how to play with his words. The fun part is that does mma and I krav maga. We don’t harm each other but it is often spectacular.
I also observed him with his friends. We have friends who are brothers and have their birthday the same day. They threw a party at home both inviting their friends. It was really surprised because at home he is the loudest of the family, but once he is in a group he gets quiet and serious. While I’m talking to everyone.
Sometimes we do us some pranks. He isn’t really creative. He once took tape and taped a few things in my bedroom. To avenge myself, I went a bit further. He is slightly superstitious. So I created this masterplan. I placed a gopro in his room where he wouldn’t find it. I connected it with my tablet. Then I placed my UE Megaboom in his closet and a little speaker under his bed. Those were relied to my Laptop and my phone. When he got to bed and turned off the light, I waited 10 minutes, and then the show began. Creepy sounds coming from the closet, then under the bed. As soon as he turned on the light, I muted them. I could see what he was doing, thanks to the GoPro. And when he got back to bed, I started again. On YouTube, I found the voice of a German woman talking like a ghost, saying that she will kill him. It was perfect. He was so scared that he went out of his room and came to mine to ask me if I heard the same things. He then realized, when he saw all my setup, that I was the one behind all of this.
