Don't know what you're missing!
Well you probably don't miss it at all. Some people like travelling, others don't. Fair enough!
I hate flying but don't mind travelling by train if its uncrowded. I don't have any desire at all to see famous sights of the world. What I really miss is the coast - its quite near to where I live, by car, but I no longer have a car. The main issue is, even if I had a car and could get in and out of it (not feasible at the moment due to legs), I can't go with Steve as he wouldn't understand staying in a hotel and the trip would involve me continually monitoring him. At the moment I can't even get out of the house let alone travel. Its a good job I'm not a dedicated traveller. I can more or less cope with living indoors (downstairs only) for now. Its 6 months since I went outside (except in an ambulance)!
When I did get away it was only ever for a few days so what went in my suitcase was minimal really.
