HI, Freddy is right, about the sleeping and kitchen and walk. Of
course, if they have a guest room, you can stay there, but then do :)
I wrote this a couple of days ago and then couldn't post it:
Ask their daughter. Just try to be yourself; they are nervous too.
(I have been on both sides :) ) If her father introduces himself
and his wife as "John and Mary", you may call them by their first
names. If he doesn't, don't, but don't feel that that is rejecting
you; dads can be reserved when meeting potential sons-in-law. Moms
sometimes can be much less reserved; they like young men, especially
ones that they think are "right" for their daughter - and the parents
will already have a preconception of you (right or wrong, they (or
maybe just Mum) will have heard your girlfriend's opinion, which will
be positive, otherwise you wouldn't be meeting her parents).
Back to the start:
"Ask their daughter": Are they expecting/fearing that you want "to
ask for her hand" at this meeting?
Let her clarify that before you meet them. Makes things a lot more
relaxed if you and they know that this is NOT on the agenda.
But if it is (assuming that you two consider yourselves engaged), then
do it; tell her parents that you want to marry their daughter. If
they are expecting that this is why you are there, avoiding the
subject looks funny, and having your girlfriend introduce it does too
(from one who knows :) ). It's the man's role, maybe not to ask,
but to tell. And then don't be too surprised if they respond with
some pretty stupid comments (been there, done that :) )
But if that is not on the agenda for this meeting, just treat them
like any other people their age. They aren't the Queen and Prince
Good luck, Myoarin
