Here is the situation as I see it:
Most of those who have posted in this thread feel that this situation is more threatening than Cakes does.
This doesn't mean Cakes is wrong, though - we all need to remember that. She's not a fool and she's met the guy whereas we haven't, and that gives her an enormous advantage.
On the other hand, that doesn't mean she's right, either. Some of the people who have contributed to this thread are speaking from direct experience. That's both an advantage and a disadvantage, though. It's an advantage because they might very well pick up clues that the rest of us miss. But it's a disadvantage because they also might project their own experience into what Cakes has experienced.
And of course several of us have thought of possible actions that Cakes didn't think of - including some fairly simple things she could easily do herself (such as getting the pepper spray or whatever, making the house as secure as possible, etc.). The disadvantage is that some of the things that have been suggested, Cakes either doesn't feel right about doing or doesn't feel are warranted at this time.
But after all those pluses and minuses...well, it's Cakes who's going to have to take whatever action is taken. We don't really want her to drop all her instincts and her experience and do whatever we say, do we? Well, OK, maybe we kind of do...but kind of don't, too. I mean, that wouldn't be right. And it wouldn't be Cakes, either.
So...just be careful, OK? For the sake of our peace of mind, maybe you could be a little more cautious than perhaps you are inclined to be? I for one would really appreciate it!
