My son works in an auto parts store and meets a lot of interesting people.  He has always worked on cars and tinkered with motors most of his life.  When he was sixteenyears old he bought his first car from money that he earned as a bag boy.  The other day he told us he was helping a man purchase some hid light bulbs for his car and the man gave him a big compliment on how efficient and knowledgeable he was on auto supplies.  He told him that he was glad he could help him and he asked him to let him know how he liked the lights.
