I have a coworker with a trigger word that can stop any argument or conversation in its tracks. That word is phlegm, totally grosses her out. Of course this is not an everyday word, especially when it comes to me spelling it. So going back to my fifth grade experience, flem seemed correct so I went with that. I was advised that misspelling phlegm would not bother her. So now I had to look it up, really ph. I’ve never claimed to be a spelling bee champ, I was first round and out on the classroom level.
