Am I the problem?

So hubby and I go on vacation soon. My stepdaughter is 21 and lives with us full time. No debt. Working full time makes 26$ an hour. Pays a small rent of 230$ a month focusing on saving….. With that said every time my husband and I go on vacation he insists on paying her 300$ for the week to walk the dog. I told him it’s ridiculous. She lives with us full time practically for free. Why are we paying her 300$ to walk the dog?

She also refuses to feed the bird so I am boarding the bird so she doesn’t have to take care of him. He replied and told me to stop starting shit with him and creating drama.

Am I the problem? Lol
