Grabbing Dews from a Fridge

As I walk off with the first can of Dew, it doesn't seem very cold, so I put it back and grab the other one. It feels much colder, and therefore, is the right one.

I can't help but think that my time holding the first can makes my fingers colder, giving the illusion that the second can is colder. I fear I'll never find the right can the first time.

(We only keep 2 cans in the fridge at a time, and replace them as we grab them. With three drinkers in the house, from time to time, they are both warm.)
