Does it get you angry when someone forgets to say Thank You to you after you have done them a favour?
Yes, it is pleasant to know your good deed is appreciated but to the point that you let it get to you so much...just because the other person does not say thank you?
My colleagues throw fits and seizures if our service users don't say thank you to them... I say Thank You as much as I can remember but I don't necessarily notice when someone doesn't say Thank you to me!
