You are not going to believe this one. Today I had my 6 month dental checkup. My dentist was going to call me about a problem she would be checking on. I said just email, that will save us both time. She loved it, said give your email address to C. Names are not given to protect the dense.
I gave my email email@example.com and then spelled it out. m i s _(underscore) j a n e d o e (at) @ yahoo (dot). com
C wrote firstname.lastname@example.org ( these are not real addresses, so the link goes nowhere) Luckily I looked at it before I left.
