I WANT TO DO THIS ONE DAY! Worth reading- this sweet gal completed 38 "random acts of kindness" on her birthday to celebrate her 38th birthday. There are a ton of great ideas on here! I would do these in a heartbeat and often, if I had money to do so. Most of these things cost money tho.
"On my 16th bday, my dad gave me a half heart necklace and kept half of it. My half was attached to my bouquet on my wedding day. At the reception, he surprised us by giving his half to Chris. He literally passed down the responsibility of holding on to my heart." (Tucking this away in case I ever have a girl.)
