I find myself accepting invites then wishing that I hadn't. Recently, a friend invited 4 of us for a catch up lunch - the date is confirmed 2 weeks later by which point I have forgotten about it and have now have things in my diary on the day before and week before including with three of five people also going to a lunch but not the host. Then I have a day walking in the Dales with three friends but the organiser has now invited four more people - I like them all (well two I find a bit trying) - Some people decline invites without reason, but I think among friends it sounds cold. But I sometimes feel that I accept something but then the actual invite changes complexion and I am stuck. Any help please?
