Does it upsets you if someone compares you to someone else?like a sibling or parent/friend...

depends on the person. So yes and no. But mainly yes

Well I can remember back to the years I would get the same teachers as my older brother every single time. At those moments I was driven crazy by everyone comparing us and expecting me to be like him when we are so different. Nowadays either ppl don’t hav3 any idea we are related, or dont associate us together

I judge everything on a case by case basis. If someone is comparing in an asshole way then yes I am bothered but if not then it's ridiculous to get bothered if they aren't being a jerk

I'm actually really liked in all of the families I'm welcomed into. Never really was compared to many people. Sorry.

I believe comparing is insulting -_-

Not really. Maybe a little if they are doing it in a condescending way to show how much one or the other hasn`t done right.
Now get this: I had a classmate that our old maths teacher constantly compared to his father and few times even mixed them up, because she had teached them both. That must be a weird feeling. :D

My parents do it all the time. Thats when I stop listening to them. It's annoying as heck.

Yes of course it hurts! whatsoever in life anything can happen, matters how wise we deal with it

I hate when people compare my dick size to a girl I just met especially when it turns out that mine is smaller

Not at all. I like being similar to someone else. It makes me feel like I have a connection with them.

A lot... but only when it's concerning my faults.
