Friend asked if I can go somewhere with them. I said sure but probably have to be next week if they want me to go with them as I am busy this week (i.e. working) and all this weekend. Their immediate response was ''what are you doing this weekend then'' ?
It just feels like an interrogation and that I need to justify my whereabouts for the weekend. I do not feel like it is a friendly curious question being asked out of showing an interest, especially as given this message exchange all took place on Monday, a whole week away from the weekend.
I will probably get flamed and accused of over thinking this and being a shitty friend for someone who was just trying to show an interest.
