Thanks DS. I ended up replying "Thanks for letting me know." I didn't say 'good luck' or 'hope everything pans out well' (who says that to an XS?). The way she phrased that kinda made me wish she hadn't bothered typing it; it was so impersonal.
Didn't bother updating her about the bills/refunds from utility companies. No response - didn't expect one.
I still can't believe she left so much stuff at the house. It added about an hour's work for myself and my family as we had to check what it was and bring it back to my storage place as obviously we couldn't leave it there (we had to be out on that day).
Yes I will keep up the DB techniques. I'm also going to always never believe 100%, or rather 50% of what XW says or does.
