Which One?? Annoying Or Childish?? Both?

1)ok.. my brother 9 y.o. was flipping channels with my [same age as him] aunt... I was pissed I lift my foot up and kicked him on the knee when I was supposed to be on my best behaviour [someone else's home]...
2)I said "I'm chasing you mommy" while going up the stairs.. a joke but she was pissed.. I'm just too old for that..
3)pulled someone's hood down during an exam.. why do I feel like to joke around at the time.. I don't know
4)calling someone's name in a childish manner [somebody I'm not close to anyway]
5)made a face while saying "it was you.. not me.." in a singsong voice
6))giggle at spongebob and the like.. this was ages ago..
7)run down the escalator with my brother..

This is more like annoying things I do list... lol.. will add more If I did it.. lol
