"helpful" people
I get really sick and tired of the way people treat someone when they say they can't do something.
For example I suck at maths, and I know I'm hopeless at it and that I am highly likely to fail any class that has slightly complex math algorithms.
And people, bless them, think they're doing the nice thing by saying "we believe you can do it!", "You can do it, it's not to hard!", "I did it, so can you!"----- these are the people that are ridiculously brilliant at maths and do not get how hard it is for those who just can't comprehend it.
I get embarrassed by not knowing how to do maths because its made out to be a big deal to know it and if you don't you're an idiot. The worst part is is when people think they're helping but end up being condescending towards you and don't get why you're being upset and nearly in tears and angry for something they find simple but you're finding it to be (insert what you find difficult in life).
