BEST GIFT YOU'VE EVER RECEIVED
I would have to say that I was the swing set that I got when I was about five or six.
My parents built it with the help of our neighbors down the street (we're actually still close with them!). They hid the swing set in the neighbor's backyard until Christmas Eve. After my brother and I had gone to bed, my parents and grandpa snuck out of the house while my grandma stayed behind to keep an eye on us.
My parents, grandpa, and the neighbor couple had to carry the swing set down the street. It had snowed, melted, and then frozen over. So everyone was slipping and sliding down the street while carrying the swing set over their heads.
(Imagine something like this, but with another swing for babies)
The next morning I woke up, gathered my family at the top of our stairs, and we collectively went down to the living room. We ooh'ed and ahh'ed over our stockings. As the eldest child, I had the responsibility of reading Santa's reply to our letter that we always left with the milk and cookies. In his reply, he said to look into the backyard for our big surprise. So my brother and I rushed to the throw open the curtains and sitting in the freshly fallen snow was our beautiful swing set.
We ran outside barefoot in our pajamas to play on it and got yelled at by my mom.
It was still the best gift I've ever gotten.
