To think taking another two kids camping would bother me?

[managedmis]

SIL asked if I wanted to go camping a couple of weeks ago, her and her DS, me and my DS. Fine, could be fun, boys get along well, we can all have a camp fire and wine once they sleep.

Confirmation text yesterday: still wanna go camping? Yes, sure. Oh, BTW the other SIL will come too, with her kids. OK, no problem.

Then changed it to SIL isn't coming, but her two kids will.

So, there's me, DS (5) her, her DS (12) and their two cousins, (12 & 14)

So I said no, it's too much like hard work, I won't be going. I didn't think it'd bother you she said.

AIBU?

The 5yo will be left out - unless the other dc are unusually nice. Well that's made my day, my grandsons must be unusually nice! I thought they were but then I know I am baised.
