We love bumping into someone unexpectedly on the street and happily lose track of time in a conversation. It's a delight when the sun decides to show up just as we were about to head off. We enjoy the uncertainty of deciding whether to catch the last chat or the last wave of the day. But what we really don't fancy is the idea of having to leave prematurely. Because, truth be told, it's not quite time yet. But we'll show up. We promise.
