Keeping up E when you make a turn in your car.
When you hear fireworks outside, you start thinking it's flak!
(kind of happened to me last night, i thought a bomb went off, first there was a huge explosion which rocked my windows. Then there was a deadly silence before the real show started)
When you see a boeing 747 passing overhead you want to call "buff over field...."
And you start guessing it's altitude.
When you see a cessna with a banner behind it. You think he will never make through the flak at that altitude.
When your phone rings, you think it's your CO, telling you there are nme planes incoming.
You have a checklist for powering up and shutting down your pc.
And,...... you search for the WEP-button on your pc, to boost your processor.
