Dilemma

Saturday night I went back to my old hometown to meet some friends for a drink in what used to be my local . Within 2 minutes of arriving I found sitting 6 feet away from me was an ex girlfriend ( I thought she was in New Zealand ) who is home for 3 weeks .

My question is what should you do if you meet up with an old girlfriend unexpectedly in a bar ?

1. give her one
2. get her number and give her one
3. talk as friends and agree to keep in touch
4. pretend you haven't seen her

Comments welcome .
