The best, possibly only, use of my latin lessons was the time I sorted out a computer problem for a snooty 2 1/2 schoolie (LtCdr Instructor Officer) who was assigned to us. "That's all very well for you technical types, but I can appreciate the joys of Catullus", said he. "Really? I couldn't be much botherd with a bloke who wanted to be his girlfriend's pet sparrow." Exit keeping a straight face.
A little knowledge can be just enough.
