Don’t you hate it when you forget things, like people’s names, how much you drank last night, pay your bills and etc ? But then again,
you do not want to remember all of it. Even Dumbledore needs to clear out his mind now and then, let along us muggles.
The way our brains function is interesting. We learn to remember and we learn to forget and sometimes our brains choose to forget.
To me, forgetting is a breath of fresh air, a new start. It feels like unloading a gun, taking off the burden from your shoulders. All you need to do during this process is to take a big exhale and the world is new all over again.
Everything is within us, by forgetting you let go of what no longer serves you and makes you happy.
