When DH used to go over to his brother's house - he would say "I'll be just a few minutes - four hours later, his *sorry self* was still there!
I usually did not mind when he went - I just minded - a lot - his inaccurate time "estimate". Especially when supper was ready - and he was advised that it was ready - and he did not show up on a timely basis. HIs brother's house was a very leisurely five minute walk away from our house.
That was oh so many years ago. I think DH would give a lot to be able to hang out with his brother like they did way back when.
I still would mind his not showing up to eat when the food was ready - especially when he had requested that it be ready at such and such a time.
