Apart form obvious things like cruelty and unkindness I dislike burned toast, milky tea, nylon, the smell of uncooked meat, bossa-nova rhythms, stickers, overly neat gardens, beige (usually), uniforms, pens that don't work, days you are 'expected' to have fun (birthdays, Christmas etc), nosey people, bossy people, two faced people, houseplants,odd socks, packaging that won't come undone so you have to use your teeth etc etc etc.
I like Hamsters, dawn breaking, fires at midnight in winter, someone surprising me by doing something exceptional, blueberry waffles, maple bacon, freshly laundered linen bedclothes, fresh cut grass, diving into cold water when hot, toasted marshmallows,littly rubbing noses with me, dogs, cats, animals in general, listening to people talking in languages I don't understand, boats, the ocean, motorbikes, forests. etc etc etc
