am i wrong for feeling like this

my friend and i were in the house sweating to death because it’s 38° Celsius, i asked my mom if we could go to the beach later, and she said “yes, if you do all the dishes” and there was basically 6 loads full there because she cooked a lot the night before, so i did them because i really wanted to go swimming. an hour later they are all washed and dried and i even made her breakfast and did the dishes after. and then i told her i was done and she said “i told you to do them an hour ago, we’re not going now” i’m upset because i’m super warm and i don’t want to be stuck in the house all day. am i wrong for feeling upset?
