Latest RAK

Where I live, my front door and my neighbors front door are about 12 feet apart.  At least once a week we leave to go somewhere and find that they have placed a tied up bag of kitchen trash outside the front door.  We do it too, put a full trash outside the door to take to the dumpster the next time we walk down that way.
When I see their trash bag sitting like that, I take it.  I walk it down to the dumpster. 
My daughter asked why I did this the first time.  I told her it was nice.  She said that was weird. 
Today when I picked it up, now the third time I've done this, she didn't say anything.  When we got to the bottom of the stairs she asked to take it.  I said she didn't need to.  She jumped up in the air and said she wanted to, that being nice is fun and she wanted to do it today.  I let her because it did my heart good to see her want to participate in this random act of kindness.
This is the latest RAK in our house.  More to come; looking for creative ways to be kind to the world.
