how did you accidently send the message? I'm a little confused
You should have thought of that before you sent it? Apologize immediately! ?
Apologize and of course say you'd never meant to send it, that is if you can't find a way to stop the message going through.
Why did u do it
Was there mean or hurtful or ugly things being said to this person? Bc u seem to be worried about the content?
Were u really just having "fun" or were u having an issue with this person? Bc if u were just having fun, why were ugly hurtful words being exchanged? If its a matter of just guy jokes explain to her that u would never talk like that to ppl but you have this humor with ur friend??? Seems like u might feel a little guilty
Try looking up to see if there is any way to stop it. I was just told there is a way to stop a message from being sent on your cellphone a few day ago (though I was not told how).
