I am sorry for the pain I caused you; I wasn't thinking straight.
An apology is the superglue of life. It can repair just about anything.
Apologies aren't meant to change the past, they're meant to change the future.
The only correct actions are those that demand no explanation and no apology.
An apology might help, but you can change your life without one.
Mistakes are always forgivable if one has the courage to admit them.
