My aunt came to stay last night and arrived about 8pm. I made a meal for the three of us. The computer is currently set up on the end of the table (not ideal but temporary measures) but it was shifted up so that the three of us had space to sit round. We were having a few drinks and chatting but towards the end of the meal DH started messing with the computer - turns out he's eyeing up the results on Sky Sports (because he's recently started placing a few bets.) I thought this was a bit off, but then he got up and went into the other room and sat there looking at Sky Sports and god knows what else in there. He did eventually come back and sit with us, but I want to know if I'm the one being unreasonable here, because personally I find this quite rude. I think if you have a guest and you're having a meal you sit there and be sociable, not wander off and arse about on the internet. AIBU?
