Obsesssive Compulsive Disorrder

Ecards for people with obsessive compulsive disorder - a switch flipped on in my head - fourteen times, off and on, just to be sure - and there it was: why hadn’t we created these yet? Of course, at first I wasn’t sure this was a good idea. Why risk offending a group of people who are really well organized? Still, at least the letters of complaint would be neatly written. On the other hand I’d have to open five identical envelopes per complaint. Finally it struck me. People with OCD aren’t gonna mess with me. They’ll might come over and tidy up around me a bit, but they’d never mess with me.

Note: there are three spelling errors in the above paragraph: can you find them all?
