Just want some time to myself -AIBU?

[Preparedtobetoldimwrong]

I work two part time jobs that add up to a full day. Am now cooking dinner and blaring out Christmas tunes. So far have had 7 interruptions from DH and DS, none of which were important. We will all sit down at the table to eat together in a bit and all these conversations could have happened then.
Would I be unreasonable to have a bath later and lock the door? Just want a bit of time for me- is that wrong?

YANBU at all except for the part where they are sitting on their arses and you are playing the saintly mother. Delegate, woman!!!

No

DH has done the shopping and DS has fed the cats (we have several) so they have done something. I do t mind cooking, just want to enjoy my cheesy Christmas tunes whilst I do it.
