Ya I collected lots of them. The boys thought I was mental at
1st, but soon enough they decided I was serious and started letting
me in on their WWE-inspired eraser game - u know, the one where u
flick the eraser with a finger and try to get your flag eraser on
top of the other.. the one on top wins and winner takes all.
Half of them must've been "converted" to "eraser dust", the other
half dunno throw until where.
Then the teacher caught me a few times playing with those erasers,
but I never got punished unlike the boys (to the protests of "no
fair!" from the boys)
Nostalgic!
