Watch who you argue with.

That sums things up pretty well...it also makes you not care very much . I am trying to help out a family member with a 318, first thing I noticed is he has the timing at 0 TDC. I said "the spark should happen a little before TDC like 5 or 10..." nothing not even a titter. He's 85 years old and likes to argue...say things like "it ran like that before..." I'm ready to say "look Ill help you but you have to leave me alone with your car Ill come and get ya when I get it dialed in..." I have realized over the years age doesnt mantter it isnt like people get smarter as they get older there are old stupid folks also...:) :)
Going through that now FIL Is 90 and just looking for a fight, even though he knows he’s wrong, he just want to yank your chain. Then when you finally break and tell him off he goes sulking, I was the bad guy, until the wife witnessed it a couple times. Then she told him your on your own now buddy. Things have calmed down a little.
