You know when someone looks a certain way, or resembles someone specific? Out of social etiquette, you don't point this out to them or say comments about them (at least not loud enough for them to hear).
What I love about children is that they don't have a social etiquette filter. They see, they say, they do, and they have no remorse.
Case and point...
One night I took Biggie (my 5 year old daughter) and Bruiser (my 3 year old son) through a fast food drive-through. It was near Christmas time and to say Biggie was OBSESSED with the season would be an understatement.
I pull up to the window and there was a large man with a white beard, wearing his red t-shirt uniform, and I silently prayed that Biggie wasn't paying attention. No sooner had we stopped at the window do I hear the back window roll down.
"What are you doing here?" Biggie asks the man at the window.
"I work here." He replied, un-sure of where she was going with this.
"It's Christmas. You should be making toys with Rudolph."
Finally catching on to what she was implying he started to get a little gruff, "I'm not Santa."
"You have a really big tummy and a red shirt. Yes you are."
The thing I love about Biggie is that she never lets anyone derail her when she's so sure of something. Needless to say, I grabbed our food and drove off quickly.
