Sometimes you tend to want things around you to stay the same, to stay as is.
You wish for love to last, best friends to always be there, summer days to remain full of parties and all-nighters, and life to remain blissful. If that were so, you wouldn't be able to grow as a person and experience everything life has to offer.
Do not fear change, embrace it, accept it.
Remember, don't try to change the things that can't be undone.
