Not sure,never really tried.
I wouldn't want to try.
Train into what? Either he's grown into a mature adult, or still a silly mommas boy. Lol
I doubt it. Good luck. I haven't tried and don't want too.
Quoting crochetmom07: If you feel you have to "train" him then you shouldn't be with him. I will never understand why women's try to change the man they are with.
train him to do what? go grocery shopping? or sit, shake, roll over?
Why would you? ...and... no you can't. Sorry, but all the work you do will not change a person unless they want to change themselves.
