I agree with that. My days are dense, long, tiring and slow, but I can't believe a full year has passed already.
Before having my daughter, days were fast, weeks were faster, and years slipped through my fingers. Time goes faster when you daily routine is always more less the same, and that is more difficult with a child.
It's a paradox best expressed by the old adage: the days are long, but the years are short.
