A few years after my grandfather died, my grandmother stayed at our house to spend Christmas Eve with us (the entire extended family would come for Christmas day). She actually came up on the 23rd, and shocked me and my siblings by jubilantly waking us up Christmas Eve with a "Christmas Eve Gift!" shout. Come to find out, it was a tradition in my Mom's family when she was growing up, and evidently in my Grandmother's childhood home as well. There wasn't an actual gift given, but was just the game of seeing who could say it first. We thought it was funny, and it became a game we took on. The remainder of her life, we would always try to call her Christmas Eve, but she realized it had to be one of us or her other grandchildren, and started answering the phone with "Christmas Eve Gift!" It became a challenge to try and say it as soon as we thought she had the phone to her ear.
Two years ago, like this year, it was our turn to have Christmas in NC instead of AL. So I made my Christmas Eve phone calls, and took up Granny's habit of answering the phone that morning with "Christmas Eve Gift!" as Dad had already got me. Only halfway through my list of people to check off, Bobby's niece called. We don't have caller id, so I had no way of knowing who it was. There was a dead silence on the other end, and I quickly realized I had a non-AL relative on the other end. I started laughing and tried to explain, but got a drawn out, "OoooKay" as if to say "Aunt Monica is totally crazy." Bobby suggests we should get caller id just for Christmas Eve, and the crazy thing is: I actually briefly considered it!
So if you for some weird reason have to call me tomorrow and I answer with a loud "Christmas Eve gift!", the proper response is to say something along the lines of "Christmas Eve gift to you, too" or "I'll get you next year!" I'm really not expecting a gift.
So now you know!
