"My sister is a lesbian and I'm gay but our parents are very conservative, so she 'dates' my bf and I 'date' her gf, so if they stay over, they stay in opposite rooms, but jokes on my parents." I love this except for the parents part.
My mom always asks me if I'm okay and my answer is always yes, even if I'm not okay. I don't want to have to explain why I'm sad, so I keep it to myself most of the time. Its really hard when you know she just doesn't care
