Ex-related dream post: go!

So, I was with Dee and we were shopping at some mall.  And he was there with his friends also shopping, and we kept seeing each other, deliberately doing things that the other would like or find funny or fun.  However, we never actually spoke to each other.  We just kept within eye's distance so that we would always have a glimpse of the other.  It almost seemed like a competition: who would crack first and talk to the other, or who would burst out laughing because of something the other did.  It was both...friendly and hostile.

And neither my sister nor his friends realized we were doing this.  It was as though it was agreed upon earlier between just us two, though I guess it happened without that actual conversation.

Eh.  Weird.
