T is for ...

... twins? Not the first 'T' which sprung to mind, but I figured I'd fall foul of the moderators if I wasn't careful!

Besides, I've just picked up a new lens today, which, from a distance, could be confused with the coffee mug which my sister bought me a couple of years ago. Every now and then I still look at it and think "Why isn't that lens in my bag?", before realising that I still haven't learnt!! Doh!
