There are some things I really enjoy but am tired of going to alone - would be nice to have someone to go with, go for a coffee after etc.
Tennis / badminton - I can't commit to a group class type thing but would be nice to have someone to go and play an informal game with
Dance classes - swing / lindy hop / jive
Peak district walks
I also like the National Theatre Live screenings / live opera screenings that get shown at the Showroom and Cineworld if anyone enjoys those!
Long shot but you never know :)
