I can always count on my dog Zelda to make me smile with her pit bull grin. Whenever I see it I can't help but smile back.
I can always count on my cockatiel Zipper to talk to me, even if it is just whistling and clicking sounds.
I can always count on our three outdoor cats Uno, Dous, (they're from the same litter) and Barbie, to come sprinting up to me nearly ever time I go outside.
