First of all, you'll be looking and smelling like a million bucks, right? You'll be smiling and laughing and having fun, right?
Just try not to let those things change if you do run into them, keep smiling and laughing, and if you see them afar, start laughing as if you just heard the funniest joke, while saying to your girlfriends, they're here, keep me from scratching her eyes out! LOL
Seriously, let your friends know that you are worried about this, and let them help you come up with a plan. Will they leave with you to find another club if that's what you need, or just help distract you and keep you laughing (making jokes about OW always helps!), whatever if is you need, make a plan and let them help.
I actually, ran into WH & OW, totally unexpected as they live 2 hrs away from where I was that night, and of all the cities they could have gone to and all the clubs in this particular city they could have chosen, they walked into the one place I was at!!! On top of that, I NEVER get out like that, dancing, etc. and this club was our 2nd choice, as the band at the 1st place didn't show!
How weird is that? I saw it as a sign. Plus WH was showing OW "our" city, where we met, courted and lived in the early days! How weird is that?
I was with a group of about 15, they surrounded me, kept me dancing, the guys in the group got real close, and my friend told WH and OW to find another place, which they did!!
Have fun! Let us know how it goes, and chances are you won't even see them!
Also, just a thread suggestion. Instead of starting new threads with every new topic, just keep posting on the same thread, and go to the first post of that thread. Click on the paper and pencil icon and edit your title whenever you need to! That way your thread grows, and we can follow your story a bit easier!
Good luck!
