Pooks has a hybrid with lower-pressure tires, she doesn't need to reinflate them at every ride. Once a week would be a good idea though.

If you have a road bike, pumping your tires at every ride is not being neurotic, it's being safe (less flats). Every three days should be a minimum. Tires don't deflate when we ride, they deflate with time, that's all.
