Dating at 11/12- what's your input?

So recently I seen people that are like 11/12 that are going out, and its making no sense. My sister (11) is 'dating' this guy and idk about what they do. What would you do, sit by each other in lunch,? I want to her how you guys feel and what you think kids are doing and if they should be dating at the young age.

Status report: I'm going out with the guy I mentioned before!!!! Yay!!!
