My friends and I started a hobby together but for me it's too long - about 5 hours, all sitting down. I feel like I'm missing time just walking/catching up/having a meal etc.
But if I pull out it ruins it for everyone else (they basically wouldn't be able to play). They could find a new person and start again, but from past experience I think it's unlikely they will, usually say they'll wait for me. I'm not sure how to pull out gracefully.
On a journey to being moe assertive so apologies if this is a really basic question!
