Flattery sucks. Problem is that I'm a bit on the naive side, so I don't always see it until it's too late. And then it really sucks because then you feel like you're a whoopee cushion that was just sat on. I don't flatter people.
Compliments, OTOH, I take with open arms.
I don't give nearly as many compliments as I should for fear that it might look like I'm trying to flatter/be false/brown-nosing etc. Another reason I don't compliment as much is because I'm a bit shy. I get this almost embarassed feeling when I do tell someone something nice...especially if it's in person.
I'm weird.
