<human>: So, for my whole life, my two siblings and I have had "soda-days." Soda days are Tuesday, Thursday, and Saturday. If we have a soda on any other day that isn't a soda-day, our parents (my dad's enforces this a lot more than my mom) will pour out the soda and essentially be mad at us. Soda days do have some exceptions, like if I was at a friends house, or if we went out to eat, special occasions, etc.

My parents say it is so we discipline ourselves. My siblings and I have generally led healthy lives. My brother does various sports (he never got interested in one for very long) my sister did gymnastics and even won state a few times and eventually went on to doing cheer-leading in college, and I've ran cross-country since middle school. For reference, currently, I'm 15.

I'm posting this here so I can get other people's opinions on "soda-days". Am I being a snotty teenager when I said that the soda-day rule isn't a very good rule? It's a nice attempt to discipline us, but I think it was executed in a poor fashion. I think my parents assume that if we COULD drink soda whenever we wanted, we'd drink a ton of soda a day, but it's hard to prove them wrong because this rule has been in place for 15 years and we haven't really had a chance to show them that we wouldn't drink soda non-stop. 

And one last note, I'll usually not drink soda during the entire cross-country and track season. It's sort of a tradition to the team to discipline ourselves and not drink soda. After either of the seasons are over, my parents still only allow me to have soda on certain days, even after I've already disciplined myself for nearly 2 months.

Can you provide a brief rundown of the text in within 3 sentences?
