The finding comes following Darren's various attempts to improve his love life, with the help of his friend Tony Hutchinso.
With Darren short-staffed at the cab office, Tony offers to stand in but soon hires himself as a permanent driver.
When Tony later witnesses Darren unsuccessfully try to chat up a woman waiting at the bus stop, he offers to help him.
Unfortunately,
Tony's help does not go according to plan and Darren later decides to
reminisce by pulling out a box of old keepsakes.
Whilst the box mainly consists of football stickers and old
bracelets, Darren is intrigued to also find half a beer mat with a
message on.
The message reads: 'Darren. You were the love of my
life. If we're still single by the time we're thirty, let's find each
other,' but who wrote it?
