The inside of the greeting cards and the other side of some Coffee Mugs says:

"You were there for me my first day of school, to hold my hand and give me courage to go.
You listened to me when I needed to talk, you talked to me when I needed to listen.
You let me grow and learn from my own mistakes.
You never left my side when I was feeling down, I knew you would be there to pick me up.
I wish there was a way I could repay all the things you have done for me, but there's nothing great enough to repay the greatest mother of all."
