Increasingly, it's friends who don't put the effort into hospitality or meeting up. The vast majority of my friends are people from university - for years, sleeping on a dog-eared chair or threadbare carpet was part-and-parcel of student life, and takeaways would make up half of our diet. Though I dread to think it, it's been over five years since I left and I have a life with nicer things, so I'm no longer happy to take this kind of thing as a given. No, not everyone has a proper bed to spare, but the least you can do for a guest is dust down the room and offer a drink on entry, or just some other forms of cheap, polite prep for someone who's maybe traveled three hours by train to visit you. Same goes for other meetups; it used to be novel to be the guy who's good at booking hotels or buying group tickets, but it's increasingly frustrating to feel like the only adult in the room and any bellyache from people who haven't made any meaningful input really gets on my wick.
Conversely, it's delightful when a friend has food and drink sorted when I visit, or they take the initiative with organisational stuff.
