The difficulty in flat shares

I had a dinner with some friends of mine in their flat.
That flat and flatmates were really nice and very comfortable, so we usually had a dinner there, but this time some flatmates didn’t join us.
Friends who joined last night told us they had trouble about flat sharing, such as how to share spaces, daily costs and so on. They looked got along with each other very well, it was a bit surprising. Some of them ware friends who has known each other before they started flat-sharing, but because of this trouble their friendship might be broken. It would be very sad.

Fortunately, I haven’t got any trouble with my flatmates, but many friends had some trouble actually. The worse cases are, like a example above, that sometimes friendships also disappear. Sharing a flat with old friends must be very fun, but you should not forget that it includes risks of the end of friendships. Anyway, if you decide to share a flat, it might be a better move to be generous even if you are right.
