I'm fed up with people who are always changing their plans

Don't you find situations in which people change their plans very irritating?
I can't stand that kind of situations. If you have fixed with someone a plan,made a plan with someone, why should it you change it? I mean, sometimes it's necessary because the circumstances may vary (you can get sick, for example). But there are also people who seem to like changing plans. Maybe they are undecided people, I don't know.

But the most irritating thing is when the plan changes one time and another and another the previous day do you mean next day?. Even the previous hour! Why can't they just go on with the original plan? I think I'll never understand that.

Agreed.
