I resolved to say all the nice things I thought. So if I see a woman with an immaculate blow dry or fab jumper, instead of being shy, I tell her she looks ace.
So if you think 'oh, that's a cool thing' over the next few days, complimenting the person out loud would be a lovely thing to do, wouldn't it?
I do like to see a smiley person.
What did you last compliment someone on? :)
