My memory stammers but my soul is a witness.

Everyone is going through something you know nothing about. You can never know the impact you have in someone else, but when you remember the effect a hug, a message, or someone's presence has had on you, you realize how profound it can be. You might change someone's day, week, or life. You may never know who held on and stayed because of you, but isn't it beautiful to think that someone did? Your being makes a difference.
