Yeah, it's definitely a thing. Pretty much everyone from my mom's side of the family is overweight, so I've heard quite a few stories. But most of them are adults, so it doesn't happen as often. My cousin, however, who's only a few days younger than me, is really overweight, and I know how much he suffers. From looks to bad comments, the guy goes through a lot, and it makes me feel awful, because I don't have that problem.
One thing I feel though, is that there are different standards for men and women. Society prefers very skinny women (but that seems to be slowly changing), while men are expected to be strong, muscular, manly. I've been made fun of for being skinny. Even though it's not as bad as my cousins goes through, for example, it hurts. A lot, sometimes.
I just wish people only cared about being healthy, not about weight.
