You bit the hand that fed you.

I shall never forget your kindness.

I owe him a great deal because he saved my life.

I'll never forget your kindness as long as I live.

I am indebted to him.

Don't replace kindness with evil.

A cat will forget three years of kindness in three days, feed a dog for three days and he will remember it for three years.

I'll never forget your kindness as long as I live.

I owe you one, Scott.

I will never forget your kindness.

Don't bite the hand that feeds you.

Don't bite the hand that feeds you.

I owe you one.
