So my DF turns 60 next weekend. The plan was/is if the weather is nice me my dd and also my sister and her ds (so max 6 people) to go to our parents house sit in the garden give presents, cards, have some food and drink etc. We’d arranged to sort and bring our own food, cups, cutlery etc and my parents have a big enough garden for us to space out.
So far the weather is looking dismal so I spoke to my Dsis and said there’s not much we can do on the day if it rains as we can’t go inside DP’s house. She said screw that I’m going in the house and that she’s not missing out on seeing our DF on his birthday. Told her straight I won’t be going in the house with my dd and she had a go at me calling me selfish and said I went to see a friend the other day so what’s the problem. But I went to see a friend on my own, sat in her garden and took a flask of tea. It’s a bit different. Am I in the wrong here?
