You took the plunge and started this thread - it doesn't take a lot of work or organising ability to start another thread suggesting that a few Epsom Gransnetters might like to meet you for a coffee or a lunch. Even if only one or two other people who respond, you will be able to meet and chat to them, and who knows where that could lead? If no-one ever started that one thread, the other GN groups that meet up would never have got together.
Do you know of a pleasant cafe ? Mention it in your opening post, something like, "Are there any Epsom grans who would like to meet me for a coffee and natter in XXXX cafe in XXXX Street, Epsom some time in the next couple of weeks? Which day would be best?"
Be brave - post it and see what happens! But do put Epsom in the thread title - a lot of people just post that they would love to meet others, but don't say where, forgetting that those reading it could be in Thurso or Tintagel, or even Australia.
