stupidity

here's the current conversation in my class...

"miss, have you ever smoked weed?"

"uh, no. i'm not stupid!"

"it's not stupid. people do it all the time."

i walk away.

"man, i had to go to the hospital this weekend...i hurt my back and they gave me morphine. i was so high! it was crazy. it felt like that time at the park..."

why me??
