. . .actually at my house it was the sound of "SEW, SEW, SEW".
The kids were talking about the family traditions and one of our traditions is to have new pajamas on Christmas Eve. With everything going on I haven't had time to make any so thus the sound of SEW, SEW, SEW, instead of HO, HO, HO.
I started sewing pajama pants after lunch on Christmas Eve and emerged from the sewing room at about 4:00 pm with 5 quickly sewn pajama pants, you can tell they were thrown together. Yep, I said 5. I couldn't bring myself to sew one more, poor Nate! 5 will have to suffice this year.
