As a child I collected coins and interesting pieces of coloured broken glass (!!). I still have the coins, and my own kids like to paw through them occasionally.
I also collected notes from my teacher to the deputy principal for being too disruptive in class - I got bored quited easily and stirred everyone up - so I guess that the depury principal collected those, not me!
For about 10 years (about 1987 - 1997) I collected the tickets to all the movies I went to see. I have a great number, but alas they were lost when my hubby and I moved house form Sydney to Orange (actually secretly I think that he threw them out as he though thtat they were rubbish!).
As an adult I seem to collect wrinkles.
