1. When you tell your wife "I only spent $50 at the hardware store but I got a lot of differnet bolts I need."
She says "$50 for just BOLTS!!?!?"
No matter how many little brown baggies of bolts you show er she just doesn't seem to see the value.
2. You need like three sizes of bolt to get one that fits perfect.
3. You can recite every dang part you touched on the car, when it happened, have pictures of it before and after, what it costs, where you got it and where the old part is... but you can't remember a birthday to save your life. "Hi honey, just go to Tiffenies and pick out something you like, here's the checkbook, ahhh just don't spend any more than 200 and tell them you need to post date that check till Tuesday."
4. "Life is like a box of Z-parts, you just never know what you're gonna need."
5. You keep telling your family, "Yes, I spent more than the price of a new car, but this one is going to be better!"
6. Your mother-in-law won't say anything but, "That little V8 looks so small are you sure it's going to be faster now?", and "Why didn't you just fix the old engine?"
7. At least two people at work tell you you're crazy, and at least two can't wait to see it.
8. You're tired of answering the question, "Why?".
So many many more...
