Friends... when I had any I used to greet my girl friends with a kiss on her cheek and I used to grab their hands softly.
For male friends the classic side hi-five followed by a fist bump and for mature friends a good hand shake.
Relatives hughes and kisses.
As for my poor black kitten I hugh her, squeeze her, kiss her cheek and I pat her butcheeks followed by some squeezing. She hates it.
For my two doggies the same but they tolerate me more than my cat. They all run when they see me.
And both of my turtles hides when they see me too.
wonder why
