The doctor tells me I should be drinking 2 liters of water a day. Do I have to drink a little bit at a time all day long, or can I wait until 4 in the afternoon, guzzle it all at once, and call it good? Would that count?
Thunder and lightning crashes over our heads. We think it’s really loud and I wonder, is all lightning equally loud? Are there big lightning bolts and little lightning bolts and some are louder than others, or are they all the same, and loudness is just a function of how near or far away the lightning bolts are?
