No I don't know how! I have a funny story though....
I pulled out of my in-laws driveway. Made it across the street and realized I had a flat tire. My DH had pulled out right in front of me and didn't notice I wasn't still behind him. I used my cell phone and called my FIL. He says no problem and comes out prepared to help me. He airs the tire up with his portable tank so I can get back to his driveway where he puts the spare on. I thank him and go on my way.
Some time goes by and we are discussing it at a family dinner. When I said he helped me his 26 year old daughter says, hey Dad, you never changed my tire. Then my MIL says do you remember you made me change my own tire?!
I had no idea it wasn't normal for him to change tires for the women in his life! When I was young my Dad did it, the like someone else said, I was married to a mechanic, now my current DH takes care of it for me! I guess maybe he thought I was too girly and might cry, he would have been right!!!!!!!!!!!!!!!!!
