thin vs fat

i'm not thin..
i'm not fat..
in the middle..
many people thinks that slim is beautiful and fat is bad...
for me, as long as u are healthy is okay either u are slim, moderate or fat.
having a size in the middle of M and L is difficult for me to buy a suitable shirt.
sometimes L is okay, but sometimes L is big for me.
sometimes M is okay, but sometimes M is small for me.
i having this problem since i was young.
on that time my parents had this problems when they want to buy shirt for me.
i just wait...
right now, i still face the same problem, and must make decision by my own self
if i go shopping alone.
guys,
either u are thin or fat
accept it because it is YOU
