Input: I am putting together a D&amp;D campaign where I going to be a first-time DM and more people have expressed interest than I am able to accommodate. I'm trying to keep it to 4 players but I could do 5, and there are two interested people whose schedules fit with the rest of the group: a coworker who has played D&amp;D with before, and someone from my meetup groups who hasn't played before.

The coworker really, *really* wants to join the campaign and has told me stuff like that she's already rolled a character and come up with a great backstory even though I've told her that I'm not sure if there is space for her yet. I wish there was some other legitimate reason I could not extend the invitation, but in actuality it all comes down to her nails.

I wouldn't go as far as to call it a phobia, but I have an extreme aversion/fear of any kind of damage or abnormality in fingernails. A friend made a comment about a certain type of injury and I literally couldn't get it out of my head for two days. Even typing this post is making me anxious. This coworker happens to have severe damage in that area and doesn't cover it at all. I don't see her much at work because our desks face away from each other but whenever I see her hands I feel queasy and it really gets to me. Currently I can't afford to go to therapy to address whatever this issue I have is.

It seems like a shallow reason to not invite someone because she is a really nice person and I know she would be a great player and it really just comes down to an aspect of her appearance, but I just don't know if I could stomach having her hands in full view for 3 hours a week. AITA if I don't extend the invitation? Am I off the hook since I told her from the start that I was just gauging interest and couldn't guaranty anyone a slot?

not inviting this girl to my D&D group for physical appearance reasons
