Okay so my group mates and I are working on a project atm. We were supposed to stay overnight at my house, we've already talked about this and came to this decision but one of my group mates said her parents didn't allow her to stay overnight at other people's house so she decided to offer to stay at her house instead. And so everyone agreed since it's convenient time-wise coz she's literally 15 mins away from school whereas I live 45 minutes away by car. But the thing is, I've already prepared the house. I cleaned and washed everything to accommodate them and so here I am feeling offended. I know it's selfish of me to feel this way but I can't help but feel offended. I don't know how to deal with this..
