There are truths to life that you just take for granted. I believe my friends will always be around to support me when I need them and that my parents will be there whenever I have a question. The reality of these truths are as thin as paper. My dad had a brain tumor removed 13 years ago and has lived a healthy life so far. The past few months, he has been sick and we found out today it is an autoimmune disease. The good news is, it does not appear to be fatal; however, it is something that he may have to live with the rest of his life.
We take a lot of things we have for granted because it's just easy to believe that things are constant and don't change. In The Catcher in the Rye, Holden loves the Museum of Natural History because the exhibitions in there are static and he wants that stability in his life. However, everything in the museum is dead and the nature of life is to have constant change. Embrace that change and know that your time here is limited. Live every moment with your loved ones close by.
