This is a tough one-and impossible to put in order. but:
Loving someone & being loved back, hugs, the colour orange, psy-trance, parties, seahorses, LSD, friends, rainbows, sunshine, The Simpsons, alcohol, beans on toast, owls, finding a one-off-bargain in a charity shop, quorn, chocolate milk, skunk, penguins, Ren & Stimpy, UV things, kittens, trees, smiles. OOps, more than 10 there I think.
