Forget, forgot, forgotten
Ahh!! It happens with me all the time. I keep something at a safe place and then forget where that 'safe' place is. All the tiny instruments that control my life have gone through this diaspora. Just to mention a few are car keys, laptop charger, phone charger, nail cutter, small scissors, coins, house keys etc. Sometimes I think that these things acquire microscopic shapes and go into hiding whenever I am out there looking for them.
