How Does Your Animal Show Affection?

Our cats have run the gamut:

Valentine who sometimes sleeps with me "like a person" and also asks to be picked up and then flips over to be held like a baby
Mr. Orange who likes to sit on my feet, and then turn over nearly on his back for a belly rub.
Recent arrival Dinky who somewhat annoyingly likes to lick and nibble on my fingers and face
(Last week, she reached up with both paws, grabbed my chin and planted one on me just like in the movies).
Vincent (who we just lost) would reach out and tap you with his paw, repeating until you petted him, and sit not on you but up against you.
Nougat (who we lost last year) wasn't much on affection, but would suckle a blanket and chastise you if you
A- petted him too much and B- didn't pet him enough. He'd also head but you.
Missy has a light "murder trigger" but will swat you as you walk by if she wants petted and you don't pet her.
She will also just fall down with a thump and expect you to come pet her
We've had a few that the only affection they showed was to follow you into different rooms.
Skittles (also lost 2 years ago) went through a period when he was about 2 where he didn't want us to know he liked us.
Basically no interaction during the day, but at night he'd wait until we were asleep (or so he though) and sneak into bed with us.
Mr. White never initiates contact of any kind (10 years), but if you reach to pet him he will meet your hand halfway and let you rub his ears. Just last month he started to sweeten up a bit and came to sit next to me. I was shocked. Once more since then.
Willow (another new arrival) also never initiates contact, but if you pick her up she will settle in and start purring immediately.
Abra (first of the 3 new ones) is my wife's cat and will get up in her face until she gets petted.
Pip was almost 4 when we lost her but was just starting to sweeten up a bit at the time.

They are all different.
They are all distinctly different and non cat people will never understand. All they see is "an old cat". Skittles sounds kinda like my Stubby (RIP) was. Aloof, but affectionate.....as if he didn't want you to know he cared. Really quite hilarious.....and highly intelligent. lol That's very much like Clyde is now. He shows affection, but it's like "if I just HAVE to" attitude. LOL
