Karen calls security on me not knowing that i spraind my foot ...

I was at the hospital for a check-up because I sprained my foot and it hurt a lot to stand, I came to check in at the counter and sat in the waiting room, I watched memes on the reddit and waited my turn until that Karen came with her son who had broken leg, all the other seats were taken and Karen looked me up and down and said "sorry young man, can you move, my son needs to sit down, he broke his leg and can't stand" I said "I'm sorry but I sprained my foot and I can't even stand I've barely made it this far I'm so sorry" and Karen just rolled her eyes and said "I don't think you're sorry enough are you really going to sit while this little child has to stand with a broken leg" I said "yes now please leave me alone" and continued to watch the mimes after a while I see Karen talking to the guard and after that the guard and Karen come to me and the guard says "is it true that you are faking that your leg hurts and that you pushed this little boy "(he points his finger at the boy who is on his mobile phone and is not interested in anything) I say "no, none of that is true, I sat down because I sprained my foot and she attacked me for not giving my seat to her son" Karen interrupted me (he tries to lie) "LIAR, we were the first ones here, my son needed to go to the toilet, so I went to help him when I came back, HE WAS THERE," the guard says, but that's not true, I saw you entering the entrance 30 minutes ago, and the young man is I was already sitting there, the doctor invited me in, and Karen was thrown out, so dad had to be with his son. soooo am the jerk for not giving her son to sit in my seat.
