No problem.
I did the same thing last week. I got an invite to a teacher thing at the state capitol. Header was “Free Teacher Workshop…” so I reply to the guy, and because most times he emails me there’s a cost to the events and it was never mentioned in the email, I asked.
Just never saw the word “Free” Doh!
(FWIW, I’m going to the capitol, so if there’s anyone near Albany, NY who would like to meet for lunch on April 6, PM me)
Gonna have some new pix, too…
