I regret I have but one clichéd response to give

I can and will leave whenever I feel like it.

My bro in-law is one of my favourite people, he'll turn up to birthdays, general celebration's and get togethers and just vanish at some point and we're all just like "yup, he's done now!" It's just nice to see him!

I have to leave for an after work social event soon. This is my future...

I have this even with friends and family...

This is me. When I'm done it's the Irish goodbye for me.

"It would make Mum sad"

I just don't go in the first place. Problem solvered.

Unless you are there with someone else who is driving and not read to call it yet. But I'll usually step outside for a while or something.

I got feet.

Most of my friends don't exactly live close by.

It'll just take longer is all.

Of course. For not friends or family I usually wouldn't even make the effort of going into a social setting where this becomes a problem.

meaning you live in a part, where you can walk within a day to your neighbors. that's not given everywhere.

here we have sufficiently constant public transport and if that's not working there are always taxis.

anyway, i guess the picture is about people who are to anxious to "simply leave"

Please refer to my previous comment.

Lack of planning. Always have an exit strategy.

Me and my wife need to just lock eyes and nod.
