To feel annoyed at people who say they will do something for you.

[Sienna333]

And then not bother?

Examples being a friend who said she would bring me back a gift from a bakery I like and then not bothering. Or those who say they will call you for a chat and again, don't bother. Why say it in the first place? Yes, life gets busy, people forget but some seem to do it all the time.
