Disclosure: I am autistic but i'm able to read some social cues.
I was waiting at the train station for the next train back to the city where my hotel was, and these two girls came up to me who were quite obviously drunk but weren't nasty or anything and tried to make small talk with me, I was polite and engaged in conversation with them and even let them sit with me on the way back to my hotel, they kept asking me if I wanted to go away with them to random places, and that they were looking for friends outside of their area. They added me into a group chat and last night they even video called me asking if I would come to out to London to see them (it was 9/10pm and I was ready to sleep) I obviously said no and they were ok about it again they had been drinking so I kind of took it with a pinch of salt.
I posted up on insta that I was looking forward to a gig that I'm going to on the weekend in which they replied seeming to take interest and to ask if they were invited, to which I said sure if you want but you know it's a long way from where you are and it's going to be metal (they didn't look like the types to listen to that music)
What should I do about this situation? Should I start setting boundaries or just kind of laugh and play along
