“Hi Dave, how was the course?” This is the sort of greeting you come to expect from fellow engineers when you have recently attended a training course. Engineers are notorious for having no “small talk”, probably because our minds are usually concerned with things like volts, amps and ohms… and why that VTR always works on the bench, but fails as s...
