Hi

I’m asthmatic. I’m currently working out. This means I’m probably wheezing. So if you hear me going…GASP…GASP…WHEEZE… this is NOT the ideal time to strike up a conversation. LEAVE ME ALONE!

Would that be rude?

I swear, I must have the friendliest face (snort) or something, because I can NOT go to the Y without having somebody try to strike up a conversation with me-usuaully right after I’ve started running on the treadmill.

I can have headphones on, totally not look at the person once…and still, they keep asking question…after question…and here I am, wheezing. Panting. And they expect me to TALK.
