cos when we are young we are waiting to be 16 so we can do this, 18 so we can do that, 21 so we can do the other! we are waiting for "events" to occur. once you reach an age when you have to take responsibility for yourself, no more ironing done, meals cooked, pocket money from mum/dad, your time is taken up caring for yourself, family, home etc so time seems to fly by because the free time has long gone!!!
