Day 22: something you collect: items collected on a mountain hike
Day 23: something transparent: the icy surface of Lake Louise, and the cool spring sky
Day 24: a perfume bottle: no perfume in the house, so some miscellaneous oils, sprays and creams.
Day 25: a musical instrument: the insides of our upright piano
Day 26: something that makes you laugh: my son, the family comedian, after a day clowning around.
Day 27: something old or vintage: a 1950s Raleigh biycle
