How were you guys when you were child

I have a 5 y/o little brother , I know I shouldn't type kids but I just can't... I can already see that he can turn out to be an ENTP ... He is very naughty and do all the things that where asked "not to do" do all the extreme things, once he poured a big bottle of engine oil into the water well ... He is very smart for his age, Acts all shy if he meets someone new and after some time he will show his true colours to them 🗿😂 ... I would like to know how you guys were as a kid

(💀 Not to mention once he rizzed me 😆 Ig it comes naturally )
