You Know It's Cold When

The dog's breath freezes on the porch door.
The dog dances around because his bare tootsies are freezing.
The hairs in your nose freeze.
You can't remember the answer to the age old question 'just why do we live here?'

Your eyelashes have icicles on them.
Your feet get cold even though you are wearing wool socks and boots rated for -40.
The snow squeaks when you walk on it.
The kids want to go outside, so you stand them in front of the door, open it, then ask them if they still want to go out. NO! they say.

Could be worse. Could be in Kazakhstan (which would be worse for more reasons than the weather):

You know it's cold in Kazakhstan when....
-You get on the bus and there is a layer of snow on the floor, as if it was outside…and it stays there for an entire week without melting.
-Your eyes tear up because of the wind and cold air, and then immediately start to freeze up, so you have to blink rapidly to stop your eyes from freezing shut.
-School kids in Uralsk went to school 4 times in the entire month of January because school was canceled due to coldness.
-You don’t even think of going outside without tights, long underwear and wool pants on.
-You can’t tell the difference between –35 degrees and –45.-Fashion (which is VERY important here) goes out the window and you wear mismatching hats, gloves, and scarves for the sake of warmth.
-Things that you don’t necessarily want to see (i.e. barf, human excrement…) remain frozen in the snow for weeks on end, unless someone chooses to chisel it out. (I’m not volunteering for that one)
-You may have to amputate toes if you don’t wear shoes that have fur lining.-It's normal to wear ski pants to work.
-You do whatever is necessary to get out of the cold, for example buying a ticket to India, where it is currently 80 degrees!!
