Just one of the many bumps in the highway of life my young friend. Here's one you got to look forward to. My Wife has that same expression "You don't spend enough time with me", this of course is right in the middle of doing a detail or something on the car. Here's how I handle it, I stop get up, go give her a kiss, walk her over to the passenger side, open the door, and take her for a cruise and a dinner. I get to keep the peace, the car and her, this way, so far it's worked 217 times in the last 33 years, for the other 1493 times it didn't, I had to buy flowers, too.
