It's easier to put up a smiling face than showing your real emotion. It's easier to assure someone things are okay than facing the truth how bad things actually affect you. It's easier to delete a blog entry than deleting certain memories. It's easier to skip a conversation than trying to retract your words. It's easier to sit by the window and reminisce all your wrongdoings than forgetting everything and just fall to sleep. It's easier to cry out of disappointment that spurting out angry words to the culprit.
But in the end, you know there's much more to life than the history and everything else will slowly get back to its place. And they too will pass. You're okay :)
