Some people say that the process of sending queries to find an agent is very similar to dating. There is a courtship element involved. Tentative attempts for a response that actually conceal a longing and hope and desire, and, whoops, the query is beginning to sound very much like a "bodice ripper." Let's not go there today.
Instead, it might be fun to consider alternative "jobs" to being a writer at the query stage. Something that captures the essence of putting your heart on the line with the possibility--more like probability--of rejection.
Here are some ideas that I came up with to start:
1) Javelin catcher
2) Crash test dummy
3) Novice electrician
4) Pharmaceutical control subject
5) Bungee cord tester
6) Great White Shark feeder
What ideas can you come up with? Feel free to respond!
