Not Palindrome

Your brain at 2AM, hitting you with useless programming trivia that will haunt you forever: The string "()()" isn't a palindrome because reading it backward gives ")()(", but "()(" is a palindrome because it reads as ")(" backward - which is the same when you consider parentheses as characters. The kind of revelation that makes you question your life choices and wonder why you're still awake contemplating bracket symmetry instead of sleeping like a normal human.
