Trying to De-thaw Plastic

So the other night at work, I was de-thawing breast milk, one of my regular jobs, and for some reason couldn't quite get the last of the dumb milk to de-thaw. Frozen breast milk is not pretty to look at because it kind of seperates out into different elements, thus I did not look into the container at the block of breats milk. Oh I mean human milk. I can't call it breast milk anymore, it is not politically correct. Anyways.. I continue to soak this container in hot water so that I could baby bar tend and mix the milk. As I kept coming back to it, it was still a frozen block. With a million other things going on, I didn't think about the time that this block of milk was taking to de-thaw. After a good couple of hours, I finally opened the stupid container. Oh whoops. It was a plastic lid sitting in there that I probably threw off the bigger container I was going to mix the stuff in. Apparently I got all the milk out I was going to get! As usual I burst out into laughter at myself, the other people in the room looked at me like I was crazy. I just went happily on my merry way, to take care of my starving baby. As I thought about it, I realized that trying to de-thaw a plastic lid was actually a good parallel to life. It's like beating a dead horse. You do the same thing over and over and over again, but the outcome never changes. You still have a stupid solid plastic lid. Does anyone relate?
