So I’ve suspected my wife is cheating on me. The usual “red flags”, she turns her phone screen away when texting, always going out with the girl friends, new underwear all the time. I try to stay awake for when she gets home, but I always end up falling asleep. Anyway, last night I decided I was going to hide under my car and wait for her to come home. Shortly after, a car pulled in and she got out while buttoning up her shirt. She then took out her panties and slipped them on under her skirt. It was then, at that very moment, that I noticed a hairline fracture on my exhaust pipe. Is this something I can weld? Or should I just get a whole new exhaust?
