i have a dance this saturday and i invited her over my house to get ready. i feel completely terrible because 3 of my other friends reminded me that i already invited them like 2 months ago and i’d totally forgotten. this girl asked me if she could get ready at my house like yesterday and i said yes. i’m overwhelmed because my mom is already going to be mad at me w 3 people, let alone 4! how can i tell her she can’t come without completely hurting her feelings?
