Har-har
It's quite easy to take a comment the wrong way, especially when you're pushing yourself so hard you're about to puke. I'm sure it's meant well, as I mean well when I cheer others on after I've finished a race (running, heh never enough time to cheer after a biking race). I've had one guy get mad when I offered some sincere encouragment at an MTB race after he passed me going up a technical climb that I eventually had to walk up. I passed him and beat him by a few minutes when all was said and done though, so I'm okay with it now
