I think it is good you offered your help...seems like the decided to come and do it when you would not be there also...maybe when he does do it praise him for the good job he has done and that you approve of his decisions on where to put things...
I think your reply was great too...
in some of the things I have been reading and listening too...when men do things alone it produces testosteron, when doing it together produces female hormones...men need testors. so that they can relieve stress...so it is better sometimes that they accomplish things on their own to help with stress reduction, also with less pressure from wife on when and how to get it done...
Don;t know if this applies to your sitch or now...
