Why should Dreamalittledream change her rare inner beauty and character because one set of parents are not as grateful as the rest? How do we know the true hearts of the parents?
That's whats wrong with this generation we all feel like we are owed something. This is a job we do and yes if parents tell us we are doing a good one than bonus, if they get us a gift from time to time than bonus too.
Yes it stinks when not everyone doesn't say thank you but thats the nature of this world.
In answer to your question yes I do my best to treat everyone with grace and respect especially the rude ones. There the ones that need it the most.
