Two persons cannot long be friends if they cannot forgive each other's little failings.
There's no disgrace in failing, lad, Though friends and foes deride; In fact, a failure's not so bad As never having tried.
Perseverance is failing 19 times and succeeding the 20th.
In the End, we will remember not the words of our enemies, but the silence of our friends.
Martin Luther King, Jr.
