If you think you're ugly but someone says "omg youre so pretty or something" and you say "no im ugly" or some shit like that, youre probably really annoying. its different if its like "no youre prettier" or something out of habit. ik some people have self esteem issues but just forever going "NO IM NOT PRETTY YOURE PRETTY!!!" is just annoying anyway i just got annoyed by this so sorry <3
