It's cold, and your blanket is too small. It's a terrible situation. Short people rarely deal with this problem. It's a curse on us taller people. It happens when you arrive at a "friend's" place and stay the night on their coach. At the last minute you ask for a blanket and they toss you something that you don't even look at until you lay down.
As you pull the warm snuggly blanket up to your chin, you feel the ghostly awful chill of the room air pinching your feet. It's a terrible feeling, usually easily resolved by getting another or larger blanket, but your host has already gone to bed. What do you do? There are a number of ways to deal with this dilemma that do not include rudely awakening your tired host.
First, try stretching the blanket. Ripping it will defeat the purpose of stretching it so don't put too much effort into this strategy.
Second, curl up in a small ball. This will work if the blanket is wide enough, but often it is not. In those cases, try not to move so at least the blanket can drape over your body.
Third, Periodically during the night simply switch from having the blanket snuggled up to your chin to covering your frozen toes. Attempt this last strategy when the former two have failed. It assumes you'll be awake for the whole night anyway so while you're awake you might as well as limit the pain as best you can.
In conclusion, having a blanket too small for your body is more then an inconvenience to your sleep. If you do not have a proper blanket, it is best you get a new one even if that means being rude to your host.
Thanks Pastor James Faris for his sermon on Isaiah 28. Verse 23 was the inspiration for this post. "The bed is too short to stretch out on, the blanket too narrow to wrap around you."
