I'm dreaming of a white... Valentine's Day

This has been the snowiest Provo winter I have ever seen. On Valentine's Day we got another fresh blanket of snow. The kids were excited, and they all wanted to go out in the snow. They all had fun, too...

except for N...

Turns out, poor N was getting sick. He spent the next couple of days very much not himself. Can someone please explain why my kids always throw up when they're sick? I mean, they don't get sick all that much, but when they do, it's the vomiting. Every time. Sigh.
