    I'll be the first to admit that I am a technophobe (对技术有恐惧感的人). Who would

have guessed that a website would help repay a 20-year-old loan?

    I'll always remember my last day at school. My best friend, Jenny, had organized a

party in the Sixth Form Common Room. Jenny asked me to go to the supermarket with her to

buy all the snacks. "I'm really looking forward to this party, Stingy (小气)," she said.

Everyone called me Stingy instead of Debbie because they thought I didn't like to spend

money. Actually, it was true.

    "There's lots of money in the kitty. Let's go crazy!" Going crazy meant buying enough

snacks to feed an army. It came to£19.90, which was a lot of money in 1982. Jenny gave

me a guilty look. "I've left the kitty money in the common room. Can you pay and I'll give

you back the money?"

    "Sure," I replied, trying to look relaxed." Neither a lender nor a borrower be" was

my motto but I didn't want to look stingy. I gave £20 to the impatient shop assistant.

    Well, the party was a great success-so great that I completely forgot about my loan

until I was flying to America the next day. I was going to live with my uncle's family

until I started university.

    I tried to get in touch with Jenny but her family had moved. My £20 was lost. Until… 

    I'd heard about a website called Friends Reunited which helped people contact old

school friends. My husband helped me log on and find my school. There she was, Jenny

Frost.

    "I'm now married, with a beautiful daughter called Debbie. Does anyone know how to

get in touch with Debbie 'Stingy' Jones? I still owe her £20!"

    We met two months later and the £20 was returned, plus interest of course. After

all, I'm a bank manager now, so loans are my business.
