Do you think this letter is sincere or a bunch of bs excuses?

.Most definitely.This is not a letter pleading for forgiveness.In fact she accepts the blame for any misunderstanding that brought about this situation.All she's asking is the hand of friendship.From someone she cares about.You can slam the door in her face and all you'll achieve.Is prove her heartfelt worry is correct,She's lost another friend.You can ignore her earnest plea and let her stew in her own misery.Or you can open the door a bit and give her hope.She's not asking you bow down and be her slave.Only can I be your friend
