Does this need to be frozen?

Last week over Christmas Holidays, I had a wonderful day, I went out sea glass hunting with a couple friends, in case you have never gone before, you stroll down the beach and look for broken glass, now this broken glass isn’t sharp at all, it has been tumbled naturally by the rocks before being sent onto land. After a couple hours of Sea Glass hunting, we went back to my friends house, where we enjoyed supper, then games. At about 10 pm (which is past my bedtime) I went home, my friend sent me home with a little bag of cookies that I was super excited about, once arriving at home, I threw the cookie bag into my freezer, showered and went to bed. After having a wonderful sleep, I got up and got ready for the day, as I was overtired the night before I didn’t clean out my backpack, so that was the first thing I did. Upon opening my backpack, I stood there in sheer confusion looking at the bag of cookies, “what the heck” I thought, “I put those into the freezer last night, why are they still there?” wondering what I actually put into the freezer last night I Walk over and open it, that is where I find a nicely chilled bag of sea glass!
