<human>: My mom randomly asked me today if I ever regretted not playing a sport when I was growing up.

I immediately answered yes, because we've had this conversation before, and it always goes the same way.

She asks me the question, and I always remind her that she refused to let me get involved with sports.

I was offered a position on a swim team in 5th grade by my swim instructor, but my mom told me that it would be a giant waste of time, and that she wouldn't take me to the practices because she had "more important things to do."

In middle school, I thought about joining the wrestling team, and she shot that idea down because it meant that I wouldn't have time to do school work, and that my team mates might be bad influences.

In high school, when I finally thought about joining the swim team, she again stated that all my team mates would try to get me into drugs and steroids because that's all high school athletes do.

I mentioned the swim team thing today, and she stated that she didn't remember ever saying that, but she almost started crying. She insisted that she always wanted me to do sports, but that I just never showed interest. I told her that I always showed interest, but she just shot it down so I gave up ever trying to ask her.

I've brought it up before, but she always denies it and claims that I'm merely misrepresenting what happened. And then she nearly starts crying every time.

I feel bad for bringing it up whenever she mentions anything sports or my grades, but she seems to want to deny anything like that every happened, and immediately changes the subject.

I hated myself for years for not getting on the swim team, but I was always afraid she'd flip out and scream at me for "wasting my time."

I want to have a constructive talk about it with her, because it's always been a point of contention for me because I ferl so cheated.

How can I do this without causing a major rift between us?

Can you condense the text into a few key points?
<bot>: Mother wants to deny that she refused to let me do sports, and I want to talk about how mad it still makes me. How can I approach this?
