I don't give up easily. Like in sports, I don't give up. I'm too competitive for that, even if my team sucks, and I'm the only one doing anything, I won't give up.
I'm stubborn too, so I won't give up in an arguement... Unless I get bored saying 'Yes, it is'.
The only time I give up is when I'm tired, bored or I just can't get the answer to the question.
