IMHO, it's not insulting, but it is a little self-centered. 24 hours after surgery is not too much to ask. A week would be different. It may be very draining on you. Taking care of someone else often is. It's important to take very good care of yourself before and after, make sure that your needs are met. I feel we have an obligation to look after one another, to take care of each other. It's important to have someone to take care of you the first 24 hours after surgery. Who would take of you after surgery? Pay it forward. But remember, it's important to take care of yourself first. "You can't stock someone else's warehouse if your's is not full." Be selfish in order to be selfless.
