Tick tock tick tock. A sound that can get on your nerves but which you soon get used to, marking the passage of time. Is it something you can't stand? Then there's digital! Table clocks and wall clocks, analogue and digital, to furnish your home with a splash of colour so you never lose track of time. It's true that there are pros and cons for clock watching: you notice when someone is late but at the same time, once they've arrived, time flies and the time you spend together is precious.
