AITA For not hanging out with my friends because i had no notice
I, 15m was at home when suddenly my dad calls me to go to the door. At the door were 3 of my friends and their bikes behind them on the lawn. They asked to come in and have a drink of water since they were quite thirsty. I wasn't very bothered by this so i let them in and they had water.
As they were leaving they asked me if i wanted to come bike with them. I said no because i was quite tired as i had a big day the previous day and hadn't showered yet today. They didn't take any offence and left to go back to biking.
My mother however was quite upset with me for not going because I spend too much time in my room. I don't disagree with her but i had no prior notice to going biking with my friends and was very much not prepared to go out today. Hair uncombed, not showered, face greasy, etc. I'm also not a very "On the spot" person.
AITA
Edit: I would also like to add that i would've gone with them if i had prior notice
