This is surprising the first time, perhaps, but eventually you don’t notice it anymore:
During a short telephone conversation yesterday, the person on the other end didn’t say “oh my God”, they said OMG. I was amazed.
The time to worry is when they start spelling out OMGWTFBBQ.
Oh, and on the middle three of that no-no nonet:
“WTF” takes five whole syllables to say what the phrase it represents says in three.
Then again, you may be in a location where one of those letters represents something forbidden. I’m guessing it’s not the T.
