Are you that happy

The other day, Mom and Ania make fun of my boobs for being too small as if it invincible or never exist.

Ania: "Yui, why your boobs too small? I couldn't see anything in there." *smirks

Mom: " You're right. Too flat. Hahahaha"

Dear both of you. To be truth, I never make fun of your physical appearance or laughing at it. But why?

So you want to say that you're just joking about it? You wanna claim that I'm being too sensitive for something like that? So what?

And guess what?
I smiled afterwards. I don't know what to respond but still I'm taking cares of their feeling or couldn't even mad to them because they're my family. How fool I am
