To feel sad for my parents?

[ChristmasBaubles]

Finishing the Christmas period feeling a bit deflated and sad for my elderly parents.
Three adult offspring. Sibling 1 didn't send a card or get a present for our parents, visited for a couple of hours but didn't really engage. Sibling 2 gave presents and spent more time with them but was grumpy and snappy. Leaving me, sibling 3, trying but not really managing to make the time special. Parents both commented to me that they are disappointed, they don't care about presents and material stuff but missed quality family time.
Should I say something to the other two about the effect they had or leave it? It's not like this every Christmas.

I have 2 siblings like this and resent them for the way they treat our parents. It sucks and feels worse at Xmas

Once the siblings are adults the parents are totally justified in confiding in them

This wasn't confiding it was bitching about not getting a card and present from one and the other one being grumpy and snappy. They could have addressed both themselves by asking if everything was alright. Surely if they're all so close they can do that? If they're not close then as PP said you get the children you raised. They sound manipulative.
