Thinking of one particular couple (close relatives) who I love to pieces and always enjoy seeing - but they just don't go home! If I invite them round I have to write off the whole day (to midnight) and I always end up feeling relieved when they go - and guilty for feeling relieved - because it seems inhospitable somehow.
AINBU if you -suspect you may be these people - please go home like an 2 hours earlier than you are thinking of doing? Even people who love you like their own space!
AIBU - if you like them as much as you say you do - you will be glad they stay a long time. You are an inhospitable grouch!
