This might be sheer coincidence. However, after your drive by comments I'm kinda thinking too.

Left work same time W does. I always check rear view mirror when this happens just in case I see her. Ok, I admit it. I made like 4 lights in a row at yellow and traffic is smooth. All of a sudden my W is 4 cars behind me. Like she's heading to our house. I'm a speeder, always have been, so I notice she's weaving in an out of traffic til she's behind me, so I take second exit and she drives on...no biggie.

I figured since she was on this side of town, she could come get her Snow tires...so I called. No answer. Didn't leave message and basically said F it.

Then I just thought, hmmm wonder if she's going the back way...so I head towards my house and go past to the other intersection and there she was at a 4 way stop, just me and her. She actually waves at me, but I couldn't wave back, I'm incredibly suspicious at this point and turn around to make sure she wasn't at house. She wasn't.

Coincidence or is this what you all call a drive by? Is this the hang on it gets better? She doesn't have a friend in this area, but could she be living around here?

I don't know. I'm not freaked out but it's interesting enough to post IMO.
