I guess it is time for a new scale.
I stepped on it this morning and it told me I was down 5lbs from my "over the holidays" weight (15 down total) I was so happy, but I wanted to step back on to check and make sure. Then it told me I was 4 pounds heavier.
Since all I did was breathe near the scale for 30 seconds, I think it might be having some issues.
Also it seems to think the air in our bathroom weighs 10 pounds.
So I guess it is time for a new one.
