When does hearing Thank You put a lump in your throat...

...when your 2 year old, while running a fever of 104, says thank you as you move the cool clothe to a different spot on her head.

... and again later while this same two year old lies limply in your arms and whispers thank you as you put her favorite cartoon back on for her to watch for about the 12th time in a row.

This being the same 2 year old who has recently fallen in love with the word HATE. In fact you have heard "I hate dis tupid thing! " so much you begin to wonder how much you are carelessly using the word hate and resolve to be more attentive to your own vocabulary.

Yup - that is when the expression 'thank you' wrings your heart.
