Comment to someone you haven't ever interacted with before or introduce yourself to someone you've interacted with and friend/follow them. Afterwards, leave a comment in this post with the equivalent of "I did it!"
I tend to be on the extroverted side of things, so this one isn't usually a problem, except this year I was wandering through the Snowflake peeps feeling isolated.
And then I encountered a friendly invitation to say hello, which I followed. :)
So thank you, friendly person. ♥
I, in turn, extend an invitation for anyone to comment here (even with a smiley face or random wave) if they need a way to fulfill their challenge. :)
Come one, come all. *g*
