REPLY:

It's not a case of "forgetting" that it was a CQ. It's a case of
tuning across a station and getting only "...W6WRT W6WRT"
The question is is W6WRT CQing or S&Ping? Can't tell, and so you have
to wait for another transmission. 

On the other hand, If you hear "...W6WRT W6WRT CQ" there is no doubt
and you can answer immediately. 

And of course, it's not just RTTY. CW contesters often add "TEST" at
the end of their CQ's for the same reason. Likewise, SSB'ers add
"CONTEST". 

As Martha says "It's a good thing".  :-)
