W made a comment about turning our front window into a bay window and so I said "That would look great, ask your father to do it" W did not respond.
I am wondering if your wife loses some respect for you when you turn to her father for assistance?
It may be in your better interest to NOT lean too much in that direction.
You can always compliment her father but still bow out :
"I know your father's quite good at this stuff, but I think I would like to have that done for you on my own in this case... Would that be ok?"
Or something like that... You would have to think on this, but how do you think your wife perceives it when you suggest she ask him to work on your home for you?
