So, my sister and I had volunteered at the local food bank the other day to serve lunch to underprivileged kids, and some of the kids thought that we were a lesbian couple rather than sisters. I told my mom about it, not because I was offended by it or anything, but because I thought it was funny, and I was happy that homosexuality was becoming more accepted into mainstream society. What was my mom's reaction? She WAS offended.
To paraphrase what my mom said: "Little kids were thinking that?! You guys don't look like lesbians!"
I replied, "What do you mean we 'don't look like lesbians'? Is there some physical distinction between lesbian girls and straight girls?"
My mom: "Well, what I mean is what they typically look like" (this was after she made a gender stereotypical comment about how men shouldn't be afraid of bugs and snakes, but women can)
The conversation stopped after that, but it was certainly interesting. I think this is one of the reasons I'm afraid to express my opinions to my parents more than I already do.
