Mmmm, cotton candy. That is another one that immediately brings back childhood memories (of amusement parks, mostly).

Oops, I have to make a correction to what I wrote:

...some other cheap souvenir that my sister loved to buy with our saved-up allowances.

That should be my sister and I -- my inadvertant word-skipping made it sound like my sister was stealing my allowance for her cheap souvenirs. No, no, we both bought them. Don't want to slander her as a thief!
