Please help me get some perspective. It’s my DD’s 6th birthday this week. We usually have a family gathering at mine to celebrate but this year DM offered to host it at her house. Only 8 of us (DM, DF, my 3 siblings, me, my DD and my DS) as DP was working.
DM wanted to do the cooking. She mentioned that she’d bought apple pie. I thought this was strange because I said I’d bake a cake. I decorated it at my DMs house and left it in the kitchen on a cake stand all ready with the candles etc.
We were eating the meal my DM cooked when my 1 year old needed a nappy change. I hadn’t finished eating my meal. I left the table to change him and made a joke about it. I was quick - maybe 5 minutes in total. I came back to the table being cleared and my DM dishing out apple pie and custard. My DD was asking where her cake was. I said “I thought we’re here to celebrate DD’s birthday. What about the cake?” My DM said she’d waited for me to serve it but I was taking too long. I told her I was changing a nappy and she shrugged.
I asked her for a lighter for the candles and she said she didn’t have one. I know she has matches so I said “oh god! Matches then!” She told me to calm down and “stop being like this”. We cut the cake and sang Happy Birthday. Me and my DD ate the cake while the others ate apple pie. I think my siblings felt bad because they each asked for a slice. My DM and DF said they didn’t want any. I said my goodbyes and thank yous and left. My DM was saying she doesn’t understand what she did wrong and I’ve caused drama over nothing. AIBU?
