Am I mature?

I have looked up on the intetnet and I have found that I am mature, except for the fact that like when I have something bad happining to me, I kind of panick and shout and scream, but I control them later. I also like to enter arguments. Also I like to eat some snacks right before lunch, as that woundn't harm anyone can it? I also like to embrarrase people in public for doing something wrong to me, to make them learn.
