How to talk to an ex...

Step 4 You're out with your girlfriend/boyfriend and bump in to them

This situation generally results in both parties attempting to upstage eachother with their respective partners. Try your best not to sink in to this because it just makes things worse for you and your ex and has the potential to damage your current girlfriend/boyfriend's relationship with you.

If your ex starts saying things like 'this is bob heee's (if they're playing that game the ee sound gets elongated in he/she) an instructables moderator (yeah I know odd thing to use but have to work instructables in....) Rise above it and reply something along the lines of ' that's great I'm glad to see you happy' (try not to do this with malice but if you must make it subtle)

If you really can't stand being within a mile of your ex just be quick saying something like 'yes this is so and so, we're just on our way back to mine/hers/his', the ex will most likely get the message or if not they just won't want to hear much more anyway...
