I did something nice and was a bit dismayed at no recognition
That sounds really sad, what was that nice thing that you did that you want to be recognized for?
I went shopping and bought the whole family some Christmas presents. Still they were not happy and just threw the gifts away because they did not like what they got
It was very nice of you to buy presents for your family. They should have been grateful for the gifts and should have never thrown them away. They should have considered your feelings.
I didn't expect that they would like the presents. Kids these days have no manners.
I'm very sorry that they were so ungrateful for your gifts. You should be honest with them and tell them that you're sad about all this.
