Legal Alien: A Scotsman in Montreal

Answers on a Postcard Please

OK, study the following situation:

Boy meets Girl who is a friend of a friend and who he hasn't seen in a long time.
Boy flirts with Girl
Boy finds out Girl lives in same city and phone numbers are swapped
Boy calls Girl and they proceed to go out a few times with other friends, but not much flirting evident
Boy stops calling Girl after a few unreturned calls
A few weeks later, Girl calls Boy asking him out for a drink - just the two of them - before he moves away and adds she tried the previous weekend and got no answer.

Got that? Right, the question is, should Boy consider it a date?
