Recently I’ve done some electrical work. I usually keep small tools in
my pockets — a screwdriver, for instance. when Peggy sat in my lap
this afternoon, she found in my shirt pockets a pen knife (she had seen
it before and knew it as a knife), a screwdriver (she decided “pen” after
examining it) and short pieces of wire (these also she called “pen”. I
named these objects – “screwdriver….. wire” Peggy imitated my names
for them, replaced them in my pocket. Withdrawing them again, she
said “pen” and “pen”, looking at each in turn.
