Nah, no bad intent here. We all have our talents and interests. You like home stuff, I like vehicle stuff.
Working on my own vehicles doesn't grow my unit bigger (no need there, might hurt the wife...even more) but I just can't imagine not knowing basic vehicle maintenance, that's all. Some folks might not, so this isn't directed at you personally.
I mean, we were all rebuilding motors, swapping transmissions, etc., etc., when we were in high school, just for fun. Ask a high school kid to do that now........LMFAO.
Americans just don't know how to take care of them-damn-selves anymore. Most people just call this or that repair man or go to this or that repair shop.
My dick isn't bigger because I can take care of myself better than someone else, but I can take care of myself better than a lot of people. Merica!
