Unusually for me I have not read all the responses on this thread, as I don't want to be influenced.
I am an organiser, and the one who 'makes things happen'. I am the one who hosts and provides cooked food and a range of drinks (I rarely drink alcohol, but provide red and white wine and soft drinks when people are at my house in the evenings), only to find that when it's someone else's turn to host there are crisps and dips, and other than the wine there is squash or water - basically no effort is made to accommodate my preferences.
If there is no local facility for something I'd like to attend, I set one up. I pull my weight, and don't expect others to provide for my interests.
I am getting increasingly fed up with those who don't. People who wait for me to ask them to coffee at my house. Or to go somewhere at my behest (so I buy the tickets and sort the transport), but never suggest anything off their own bat. Basically, people who expect others to run after them and can't be bothered to reciprocate. They are a drag on everyone else.
A while ago, I decided to stop doing it. I made a conscious effort to make new friends, and I made it clear to the new people that I wanted to be friends on an equal footing, and it has worked.
I still see my old friends, but I make far less effort. I don't dislike them, but am not prepared to carry their social lives any longer. Mostly, I go out with the new people, and have met even more new friends through those people, as they are the sort to have people in their orbit - the old ones just don't, as for years they have sat back and waited for others to make the effort.
So. I'm not sure what has been said, and I am not responding to anyone in particular, but if you are they type to expect others to do the heavy lifting, maybe you need to have a think?
Why should it always be the same people who bother, and why do some think they are above making an effort?
