My FIL used to say if you can't do it right don't do it all. My FIL took one of DHs younger brothers to school and dropped him off. He decided he didn't want to be there so he walked home. When Mom(MIL) found him at home she asked him what was wrong. He said well Dad says if you can't do it right don't do it at all and I can't do my math right so I didn't do it at all and I came home! LOL He didn't get away with it but he tried!! LOL
