What kind of trouble am i in, i saw a friend yesterday and i told her Hey, great costume you look really….?
cool with those old, worn and torn clothes on
did it take you long to fix them up that way?
She looked at me with a puzzled look and said you A** H****
these are my regular clothes, i haven't got ready yet!
oh crap!
So she was mad at me big time.
how do i fix that one?
giggle , oh man, that’s not cool at all,
but you know what, just tell her, that, your sorry, truly sorry giggle,
that you where joking and the joke got out of hand, that your friendship means a great deal to you and you do not want her to be upset with you
and wow giggle, watch what you say, to people, gosh but i do have to admit that is a little funny giggle giggle, sure you did feel bad, wow, giggle well i hope i works for you, and i am sorry that it happen to you,
but its a lesson learned

Tell her you were just joking! and apologize.
Apologize apologize and apologize some more
Your just an awful human being… jk
Good luck hopefully she forgives you
You are funny…you can’t fix that..goodluck!!!
Say you’re sorry, and offer to buy her some new ones the next time you’re at the Salvation Army.
