Uh, no, because dating doesn't really mean anything in third grade. Six and seven tahun olds can't exactly tarikh like fourteen and fifteen tahun olds, so no harm done!
Wow, well no harm done, I was once forced to Ciuman my cousin (whom I knew was my cousin also I was twelve at the time) to get out of a locked closest and that's certainly worse than accidently dating your cousin in 3rd grade.
