Rain's equal?

I have been trying to think of themes for a possible sequel to "the smell of rain when it's raining". It has proven extreamly difficult. The idea of rain in the first gave the play a sense of romance, beauty, calm, thoughtfulness and innocence all wrapped up in one. I have found it very hard to come up with something else that would do all those emotions justice. Those feelings in "the smell of rain when it's raining" are so strong, that they should be mimicked in it's sequel, but (of course) in a different context. If a sequel were to occur, we would need to find something that gives the play those same feelings, but provoke new thoughts, and really make the audience contemplate life, especially if they saw the first.
I don't think "snow" would do it justice at all. snow has a comlpleatly different feeling than rain, and I think especially in Canada, we've all had enough of snow.
Of course, what we're looking for dosn't necessarily have to be related with the weather at all, it could be something like ... pencils. And the entire play would concentrate on the existence of a pencil - which would keep coming up in the conversations of all the couples, and among friends. Sorry, pencils was the first thing I thought of.
What about Christmas?
In any case, it's something to think about.
