Met a man at an event a few weeks ago. We spent a long time talking, he seemed very pleasant, we had quite a lot in common. He has emailed me a few times, now has asked me to go on a walk with him. It is a group walk so (hopefully!!) it won't be just him and me. I am just a bit nervous, as I can't say I really know him. I'm sure it's Ok and I should just go, enjoy the day, and welcome the chance to make a new friend. What do you think?
