Yeah, reading this, my hopes are dashed and I think it's time to move on, lol. I actually did do this to this chick at least once back when it was more viable to take my lunch break in the main room where she did (and probably still does). And I may have done it again one time she randomly popped up at the break room that I use and usually don't see her at.
Actually, a few days ago she "surprised" me and sat in the breakroom I use again but I had the good sense to avoid sitting anywhere near her this time. The two times I've seen her at that breakroom she's literally in one corner while I'm usually in the opposite corner on a daily basis. That day my normal spot was taken but I took an open spot close to it still far away from her.
