I'm not crazy am I? I arrived at a social event, where I was looking forward to seeing my friends, and having my DS play with my friend's DD, and am informed by BIL that Nana is on the way to look after my DS. Without asking me or DP. When as far as I'm aware she has no intention on joining in the event.
I came home because my laid back afternoon with friends was no longer that.
I'm not U to think that if you want to see your DGS, you ask, not just gatecrash a fun afternoon!
