I took your original comment about the quadriplegic car as being serious so it got my back up right away. Coming up with weekly combo's can be a chore sometimes as you're trying to please as many as you can, so when I read that I reacted the way I did. I've also been a headache riddled BOB all week, so I'm not in the best frame of mind to begin with.
A good thing to do when you post something like that, which could be taken the wrong way, is to use Emoji's (the little smiling face in the top bar

) or a simple haha or lol. Sometimes it plain obvious when someone is being funny or sarcastic, other times it's not.
