A few days ago, I was visiting my brother in his garage, and he told me to hand him a tool, and I didn’t know what he was talking about.  I was fairly embarrassed, and I told him that I didn’t know which was which.  At one point, I picked up his olympus borescope, and asked him why he would have a medical tool among all of his automotive tools.  He grabbed it from me and told me to go in the house and help his wife make dinner.  I needed to earn the right to be in his garage.  It was humiliating.
