Accidentally Coming Out

Hello, I’m a closeted bisexual and I keep almost coming out to my parents. They wouldn’t care much but my mum just doesn’t understand that it is possible to be bi. My mum also keeps commenting on how straight my teeth are (I’m toward the end of braces and she’s a bit obsessed with the progress) and every time I almost say that they’re straighter than I am! Which is true! 😂. Hell, I’ve known I was bi since I was like 12. It’s been a while. I kind of want to come out but I’m scared…
