When I'm tired, excited, or hyperactive, my Aspie traits are proterburant, just like Silas Marner's eyes. I can stim (if you count shaking your legs or clapping your wrists a stim), I will be brutally honest, and my humor becomes extremely obscure, odd, and completely undecipherable. I will also have a larger and more expansive vocabulary and memory, but it lasts for only a second until the hyperactivity kicks in (that's always at night).
