As many of you folk who attend conventions and Autographica events will be aware, guests are always more than happy to have their photo taken with you, like this one showing the affable Shane Rimmer with yours truly, which was taken by my pal, Andy Kerr.
Andy took this shot while I was having a friendly chat with David Graham and David Elliot.
However, things can go in any direction when mischievous Matt Zimmerman gets involved.
He's just so full of fun. He couldn't resist photo-bombing a picture of Jeremy Wilkin and me.
I just had to have photo of me and Matt together!
