One day, someone told somebody else:
- Damian Conway is a great speaker. If you're ever in the vicinity of one of his talks, say 2,000 miles, you should go there!
After the talk, that somebody joined the Lisbon Perl Mongers mailing list.
A year later, Damian returned to Lisbon and, sure enough, when he presented his "Quantum::Superpositions" talk, that somebody was there again.
After the talk, that somebody came to me and said:
- OK... Where should I start learning Perl?
And that is the kind of thing that happens when Damian comes to town.
