Hypothetical: You meet a guy, hang out, have a good time and he takes your number and doesn't call. Do you find his number (internet?) and call him up?

I have a sort of debate on another thread with another Jelly. A girl asked about a guy who she thought she had a good time with. The guy took her number and did not call her. The other Jelly suggested she look him up (White Pages, internet, whatever) and call him up.

I don’t agree. I think that’s hunting him down and his not calling would deter me from seeking him out.

What do you think?
