to be often forgetful

I used to forget when my room was a mess.. But recently I started the habit of cleaning my room regularly and now its easy for me to find my stuff cos each and everything is where it is supposed to be...

Before I never used to remember where I had kept my things.But now when I keep things away from their normal place, I make it a point to tell my mother about it.

yeah!. i am really forgetful. sometimes i think that i have short term memory loss. well sometimes i get really forgetful that i hold a thing in one minute and the next minute ill try to remember where i placed it. it gets really distracting and annoying at times because i forget where i put my keys and i have to go over the place just to find it causing me to waste time and effort. sometimes too i forget to bring the keys in my room that i accidentaly lock myself out and i have to climb the roof and enter from my window just to get it. its so embarrassing. i wish i wont have days were my memory is really really short.. i hate it.

No, I don't forget things very easily.
My memory is very good and I always try to leave all my things in their appropriate place or in a very visible place. So, when I need them I can find them soon.

All the time, i forget all the time, i'm even teased that i am older than my grandfather since he doesn't forget and i forget.. i'm not sure what's the cause of this, i mean, i'm only 19 and i am already forgetful.. is this natural?
