You can use it alright, but I can't guarantee the results would be the same. The subject is hard, man, some parents in law are waaaay into this babies thing.
Hey, maybe I will be the same in my time, who knows? "We are not talking about your children here, you know? We are talking about my grandchildren! So stop being such a slacker and get on with it already!"
Hahaha! I get what you mean. You're probably right. My wife has been orphaned for a few years now, so in-laws aren't that much of a problem for me.
