Engineers have different objectives when it comes to social interaction. Important social contacts. A feeling of connectedness with other humans. Avoid getting invited to something unpleasant. Demonstrate mental ability and mastery of all subjects.
Engineers like to solve problems.
If there are no problems handily available, they will create their own problems. Engineers believe that if it isn't broken, it doesn't have enough features yet. No engineer looks at a television remote control without wondering what it would take to turn it into a stun gun. No engineer can take a shower without wondering if some sort of Teflon coating would make showering unnecessary. I don't want to be away from my job that long.
