@ a few posters: I never asked Lodger were she was going to next, and I don't really care and to be honest I don't want to know. Her mail can be re-directed by the post office, a service that you pay for. And once again, I will presume here , Lodger will not want to pay for that and will expect me to forward her mail onto her. Yes, I will do it, BUT, I will not suggest or offer to forward mail, Lodger can remember to ask me, before she goes.
OP, even now she's moving out, you're still acting like this girl's mother.
Either forward her mail or don't. But don't play the 'ask nicely, now' game with someone you allegedly have a business relationship with. Even if it's only one you're playing in your own head.
I really think that you need to look at this dynamic before you take in another lodger because I think it's a big part of the problem you find yourself in with this one.
I find this reply quite hurtful. Until a PP mentioned the mail I had not even considered it, not on my radar at all. If I am acting like her mother, than I would consider myself a very poor one - I do not do anything for Lodger, I don't give my opinions or advice to her, I keep my mouth closed because she is NOT one of my children. Heck, there was no nagging about the dishes in the drainer, I asked her once to move them and that was it. I care as much about her as I care about anyone I barely know, that is I don't want harm to come to them, I act respectfully and kindly and I will do the odd favour, if it suits me.
It is very hurtful and confusing as I truly know that I am not treating her like a daughter, so I asking everyone to knock it off.
