Why do people keep telling me "I'm crazy?"

Ok, so today I ended up doing 3 spin classes. I taught one at lunch, then after work, I went to one of my gyms downtown to teach... but no one showed up (not unusual for this small gym) so I left... went to VIDA and took 2 spin classes in a row =) . Hey it was fun, and I needed more practice on the real ryder bikes they are so AWESOME, but I want more practice before I teach on them. Then of course I went to my normal Monday nite dance...
Yes, I know I'm busy and always doing something... but come on people... I'm not crazy =) I'm ....uh... there's gotta be a better word than crazy....
