Where am I?

I must apologise, to myself. For the span that I've been away, from myself. For I am perhaps the only one in this bright, cozy, cool room from where I can see it rain outside, when I so desire.
I see no cobwebs here, no dust. It is as though I was expected each day, to this room of my own. I am a man, and I too need a room.

I have felt a deep longing for this room, now perhaps more than ever. I will not reveal why. Open the cupboard in that corner and you'll know. But I will not unlock it for you. Let it remain therein.

If there were other inmates here, they would not have recognised me today. I know, because people have told me. I have looked at myself too. There are mirrors here. But I do not know how true they are. So maybe I don't quite know. I am glad this mental institution houses me, and me alone.
