You are on the hunt for a teeny, tiny cache. It is hidden somewhere in not-so-teeny-tiny London. But where? To derive the final coordinates, please solve the following puzzle.
To find this cache, you have to think outside the square.
things
You have to tax your brain.
are
You have to theorise.
sometimes
Hypothesise.

Use logic.
they
Common sense.
seem
Use your puzzle solving skills.
If you bring all of the above to the table, you will end up with a teeny, tiny cache in your hand that has no pen or other contents besides a log. Hopefully, you will sign that log and be on your merry way.
Happy hunting!
