Ah that's great Chewbacca, good for you!
Coincidentally, I'm feeling a bit put out about a party myself today. We are living in temp accommodation near my DS and Dil and DGS. Whilst we have been here (5 months) I have looked after DGS 3 days a week while DIL works, and in the evenings whenever they need me. No problemes there, I love having him. This weekend, Dil's mother is visiting, staying at their house. I heard Dil ask her if she could babysit on Saturday night so she could go to a colleague's 60th birthday party. She said to her mum "unless you'd like to come to the party?", and her mum said no, she'd be happy to babysit.
This morning, Dil texted me and asked if I was doing anything tonight. I said no, thinking, how nice, she knows that I don't have any friends here and, knowing I am the same age as the host, is going to take me to the party. So the next text reads "Great! Can you look after DGS as my mum has said she'd like to come to the party!"
Walked into that one!"
