How would you feel about your childs teacher drinking while on vacation?

I'm appalled by this! Of course a 24 year old teacher should be allowed to have a glass of wine and/or beer when she's on vacation. Why should she not? She is over the legal age for drinking, she isn't at work, she posted the photo privately, and she did not encourage drinking to her students. There is no way her students would ever see the picture if it was posted privately, and even if they did, why would it matter? She's over the legal drinking age. Are these parents teaching their kids drinking is not okay under any circumstance, at any age? Good luck enforcing that rule!
