Am I pushing too hard?

My parents are doing a lot of work at the cottage.

A. LOT.

Cleaning, fixing, painting, moving, cutting, lifting, more fixing, scheming, washing, supervising, thinking, dreaming, more fixing.

I worry that it's too much. That I'm being a terrible demanding mooch.  Especially when things like this happen.

That's Dad, napping on a chair pad on the porch. He does have a bed. There's even a comfy couch in the living room. He said he liked the breeze, the shade, and the sound of the water in that spot. *sigh*

Am I pushing everyone too hard?
