Thank-you email that almost made me cry

We sold our daughter's crib via Craigslist last night. The father of the child came and picked it up. The mother could not come, but she was the one who was communicating with my husband about the price, pictures and condition of the crib. The mother sent my husband a thank-you email today. I was in tears after reading it. It's the little things in life that count, and make us feel once more that this world is not a bad place after all. Here it is below (I did not make any changes to it except removing her contact info):

Hi,

Hope you are well.

First and foremost I want to apologize that I was not able to make it last night to pick up the crib, I really wanted to meet you and personally thank you.

I am so happy to see my daughter sleeping in a beautiful and most importantly safe crib. Your generosity about reducing the price for us and adding extra items have touched me, I went to sleep last night with a huge smile on my face, I had a hard time falling asleep; because I was really happy. My Brianna will be sleeping on it for years to come and once she is old enough to understand, I will teach her about kindness, and share this experience.

If in the future you have other items that your daughter no longer wear or need, please let me know, email me directly: ...@yahoo.com or text me at xxx xxx xxx before you post them on Craigslist.

Again, I am very grateful. I wish you and your family all the best.

Kind regards,

Cris
