Mark Twain said that one can enjoy a rainbow without necessarily forgetting the forces that made it.
It would be even too easy to repeat that, after a storm, either metaphorically or in reality, there is always a rainbow to apologize for it. Actually it’s not the case, alas. Sometimes being necessarily always optimistic at all cost is not exactly the best attitude, even though it might help in the short term.
Nevertheless, when we have the chance to enjoy something beautiful, although temporary, we can take advantage of the precious moment.
