Isn't it typical. Just when I have my head in the clouds about one guy, another guy decides to register his interest with me. Also why do things like this happen when I've got a whole heap of work to do thus can't spend the requisite hours daydreaming, delibrating and cogitating.

I do sometimes wonder about relationships.

It seems to me that timing is a huge factor. You can spend about a year, I think it was, drooling after someone hoping, praying, getting really drunk and boring all your friends about how wonderful he is but then slowly but surely your desires fade and you reconcile yourself to friendship and someone else becomes the object of your desires.
Sod's law practically dictates that it is at that point that the first guy asks you out.
