We celebrate at our house on Christmas eve morning. So it was perfect that on the Eve of Christmas Eve at 9:45 p.m . there were a series of popping noises -- I was thinking firecrackers, my husband was thinking gunshots -- causing Mr. Big to run in and inform us that he'd just heard reindeer feet running on the roofs. Ear of the beholder.
P.S., turns out it was reindeer, since no police sirens followed.
