Some change of plans, I might be able to join, but only for the first 20 minutes. Is that ok? If the places are all taken, I will ofc leave it for him/her instead but otherwise, may I join?
and this is going to happen in about an hour, right?
EDIT: ofc it's going to happen in two hours =) then I'm afraid I won be home, so strike my place... My familly has a table booked at that time...
