I, with my dad, was going to Staples, to get some pages printed to get money from my RESP. An HB6 was at the desk, nametag reading "Kara", and I told her I needed a document printed from my flash drive. She opened it up, asking

Kara: Are you going to Waterloo?

Me: Yeah.

Kara: What for?

Me: Computer science.

Kara: Oh, cool.

She gave me the pages, I paid her, and she gave me my change. I began to leave, then turned my head slightly back to her.

Me: Are you going to university, too?

Kara: Yeah, Guelph!

Me: Oh, cool! My sister goes there, and a friend of mine too.

Kara: A lot of my friends are going!

This was our entire interaction. I went to find my father, give him the documents, and help him out with laptop selection. We left.

Question #1: In your opinion, was she interested?

Question #2: What would you have done?

Question #3: Is it worth going to Staples again? I'm biking to within 5-10 minutes of it anyway tomorrow (a 20 minute bike ride in total, from my house). If I'm already nearby, is it worth going back, and checking if she's there. (If you don't think it's worth it, know that I might need another copy of the documents anyway; in that event, is it worth opening her while I'm there?)

Question #3b: If I do encounter her again, how would you open, in my position? I'd go with "I feel I missed an opportunity, you're really cute." (Depending on how I encounter her, there might be a few sentences before this).
