As a family with young kids, we only celebrate Halloween with fun stuff. So only smiley faces for ours! Or whatever it turns out looking like after we have butchered it while trying to carve.
I love the smiley faces, but thought my ds would like to see a scary one for a change too... he arrived (from abroad) to see the pumpkin lit up at teh streetside waiting for him.... one side a smiley & the other side a scarey face.... it is cute. He loved it.
