wrong

David:

I feel for you. You get picked on a lot around here. I want to offer some advice.

Next time you want to do something related to a car at all, think to yourself "Would David do this?"

Then do the opposite.

For example:
"Would David steal a used fuel filter from the junkyard?" (with his mom, lol)
"Yes"

then what you should do, in that case, is not steal a used fuel filter.

Simple rule. Try it out.
