I may have done something I shouldn't have done on Christmas day.
Oh really? What did you do on Christmas that you think is wrong?
I should have told the truth... or accepted what happened.
While it's good that you now are thinking back on your past actions, you should not do things that you know are wrong. It sounds like even at the time, you knew it was the wrong thing to do, but still chose to do it. In the future, you should do the right thing so you don't feel guilty.
Goddamn y' all keep judging... really makes me feel better.
I'm just saying that in the future, if you know you're about to do something wrong you shouldn't do it. It's still good that you acknowledge that you did wrong, though!
