Fun topic!
Here are some "pairs" that I found in my photo collection...
In London
Tower of London
Mother and baby (friend's horses)
My friend's Malti-Poo dogs
My Aunt's cats - Devon Rex breed, the white one passed away recently
Taken this morning at the AIDs LifeCycle send-off (my roommate was riding)
Pair of buildings next to where the Twin Towers (WTC) used to stand
A very old picture of my childhood cats, Sasha & Pandora
And finally, a few pictures of my Ball Pythons - Delilah & Tobias
