Your reluctance to answer certainly suggests that she's fat.
I can either say shes fat and have you put it in your sig (my god I just realized how pathetic that sounds)
I can say shes a supermodel and have you call me a liar
or I can say nothing and leave you totally unsatisfied
kura, if I were you, id worry about how fat my own girlfriend was. Well, I mean, hypothetically, assuming you'd be able to convince someone of the opposite sex to engage you in conversation.
