Is AUTHOR wrong in the post ? POST : So to start off I'm bringing my friend to a very small Comic-Con for her birthday. We had planned to go together as a pair, but she wants to bring another friend. 
I don't know this person at all. I don't know what they look like or anything. 
My friend has a tendency to stop talking to me in favor of talking to other friends, when it's just us hanging out. She took a call with internet friends when we were at the pool.
Anyway I feel like I should let her take them, but at the same time I don't want to be left in the dust.
So WIBTA if I said she couldn't take them?
