Is kissing someone other than your significant other under mistletoe considered cheating? That, apparently, depends on who you ask. Most people believe it is, according to a survey published by Yougov. 27% of male respondents say it's okay, but only if it's under mistletoe. 23% of female respondents say it's all right. Older folks are reportedly more okay with it than young people. 41% of people over 65 say it's all right, as opposed to only 17% of people under 24. Sounds like a bad idea to me.
