My mother is now having her latest sulk because my inlaws are buying dd a bike for Christmas when she wanted to buy it. In actual fact it was me and dh who were planning to buy her it and my mum offered to help with the cost if needed but that's all she said. Then out of the blue my inlaws announced they were getting dd a bike so we had to change our plans. My mum has reacted badly - not speaking to me for a couple of days even though it's not my fault and now she's saying she's not going to tell anyone what she's now buying for Christmas in case "someone copies her". It's silly and infantile - my inlaws didn't copy her, they just didn't know she had offered to help us if we were struggling to afford it. She always sulks when my inlaws but something and then buys the same thing herself anyway so dd has two of the same thing all the time!!! It's getting annoying and embarrassing and takes all the pleasure out of giving and receiving!
