I have always tried to be very honest with family and friends and when meeting new people who seem to be people I could be friends I find a time to say to them. I dont say things that I dont mean, so if I said I would take you somewhere and then when you ring I say have a doctors appt or something that will be true. I dont make excuses, and similarly if they dont want to go to something I have suggested I would prefer that they say so. That way you dont end up doing things that really neither of you enjoy. For example I will offer to take someone into town and arrange to meet them for coffee later in the morning. they can go window shopping or whatever and I will do whatever I went to do. I hate spending more time in shops than I have to but am happy to give the person a lift. It can be a bit awkward in the beginning but it works out well and we are able to enjoy some time together and not waste time doing things we dont like. With families you can have the situation where different members dont know the sort of schedule of the others or feel that they cannot say that they no longer like doing x or y. When I lived abroad we came back for about a month, and people would say how nice to have a months holiday, but in that month we had to sort out legal issues , check the house, see doctors or dentists etc and the family were all over the country but expected us to visit them all. I managed to organise that we all met at the swaledale festival which was last week in may and first week in june. We managed to get everyone there for a sort of core weekend and the monday and tuesday. Parents stayed in hotel, sister was camping etc. There were lots of different things to go to , guided walks, recitals , concerts poetry and all sorts of things so we were able to mix and match with each other and let the cousins have some time together and we met up for meals in the evening. It worked out well, gave us chance to see each other but not overpoweringly and for us it meant we saw the family all within those few days and actually had a whole week left for ourselves!! No one had the stress of people staying and catering for large groups , you could avoid someone for half the day if they were getting very annoying and still kept some family time and even allowed me to have some time with my sister in a workshop we enjoyed and with families it was years since we had had a couple of ours just to ourselves. I do think it is worth risking getting an answer that you do not like to actually find out what people like and what may be causing them problems etc and you might find something that you had not thought of before, so again you can have that situation where you think they are fobbing you off and they think they cant ask favours of you and so you all feel stressed and possibly sad but you may not understand the situation. As grandchildren grow up they may become interested in something that you are experienced in and then you may have something in common. I wish you good luck and the most important is keeping in touch with them all
