W:I thought you'd be studying for the exam and maybe I can study with you.
M:Oh well I was just taking a break.This math thing gives me a headache.
W:I know what you mean.I've been working on it for 3 hours already.I'm beginning to go impatient.I'd been thinking of the sample problems.I just don't get some of them,
M:But I can't believe you were coming to me.I mean you do know what I got on the last test.Don't you?
W:Yeah,I know you told me.I just thought two heads might be better than one.
M:Yeah,that's a nice idea,but you know I wish I knew the girl in our class who got 100 on the last test.She didn't miss a question.um Was it,Elizabeth?
W:Oh yeah Elizabeth?Why don't you give her a call?
M:Good idea.Could you tell me her phone number?
W:Okay.
