Answer:
Absolutely not
Explanation:
Stacy was a legal adult at the time she was in the photo. She was drinking out of a plastic cup that could have had anything in it. The contents of the cup were impossible to know from the photo. The argument that it could have upset her students is a very invalid one. Most children have seen their parents drinking on occasions throughout their lives. I do believe that teachers are held to a higher standard, but what they do in theor private lives should be their decisions as long as it is completely legal and not vulgar or discriminative.
