Mother in law and her teenage son have lived with me since August. The level of disrespect and "logic" that has come out of his mouth would make any man cringe. I would take him out back and beat the breaks off of him but my wife says it wouldn't do him any good. I told her I would be better though.If that is your only complaint, you haven't been married long enough. Let your mother in law move in with you for 9 months and you will hear complaints. Just remember we aren't perfect either. This is from an old married man getting ready to celebrate 31st anniversary in a week.
And yeah, I get tag teamed at times with my wife and mother in law. They find something they want to do and then come at me together saying we should do this, like buy her teenage son some $150 shoes or build some ****ed up art thingy they found on Pintrest or move furniture in a spot that makes absolutely no ****ing sense. Sad part is when most of the time when I say no, it's still done anyway when I get home, and they still want me to actively support that decision...
