My husband is into the whole Microsoft Flight Simulator world, which is apparently a rather large world with organizations and ranks and events and training and barbecue suppers and satanic rituals and what have you. Now, this obsession (oh, I meant hobby) of his doesn't bother me except for a) the sickening geek factor of the whole thing and b) the fact that when he is talking on his little microphone to his little flying buddies they say "tree" instead of "three". Now, supposedly this is some linguistics issue - it is easier to understand "tree", but I really think it is just to amplify the geek factor.
And the correct answer to the question "will he ever take real flying lessons?" is "over my dead body".
I'm sure that can be arranged.
