I'll let you know when I'm safe and sound.
I'll miss a lot.
You have a special place in my heart.
How could I possibly forget you?
It's been great/a pleasure knowing you
Catch you soon!

You can bet your life on it.
You can bet your bottom dollar.
Don't count on it!

He eats like a horse.

She's a fox.
He struts around like a peacock.
She's slipperry like an eel.
He's shrimp.
He can memorize like an elephant.
