Never. Partly because I have two older brothers (I'm 21 and they're 33 and 34, very useful when you're a kid), and since I'm kinda tall and big (1m84 / 104 kg), people rarely want to fight me... Also, I'm very skilled in avoiding dangerous situations I got one or two problems with guys who thought that I was hitting on their girlfriends (not my fault if they sucked at relationships and that I'm a good listener) and with a "funny guy" who painted my letterbox with chocolate (real chocolate, not a metaphor for sh** ), but nothing really serious.
The only times I actually hit someone were when I was 5 or 6, someone broke my glasses and spat on me (he got a nice punch in return) and some guy who was making fun of me (he really pissed me off) when I was 8 or 9 (I choked him, threatend him, then I threw him to the ground in front of his mother)
And my friends told me I'm really scary when I'm upset
