How much older do you have to be than someone to refer to them as little, or "wittle" in my situation?

u shouldnt be made becuz she is admitting that she old.....which old ppl usually deny it.....and actually if she act that way then she is the little baby one not u..........and dont send her url or slap her becuz that just prove that her plan work by making u mad and loose ur control...there r still many chances u can get revenge but in a different way
