Look at the time! We'd better go or we'll miss the train. It's my mother's birthday today so I'd better phone her this evening. I've got an exam tomorrow so I'd better go to bed early tonight. You'd better take an umbrella if it's going to rain. You'd better tell him the truth before someone else does. https://339efcb25eb75e967b0d-ff8eeadd950d51fd1fc939dca75b3973.ssl.cf1.rackcdn.com/assets_green.swf
