I have lots of questions:

What if the pre-image starts in between the parallel lines, is reflected over L then reflected again over M?
What if the pre-image starts on the far side of M, is reflected over L then reflected again over M?
What if the pre-image starts on the extreme far side of L, is reflected over L to the far side of M, then reflected again over M (which makes it go 'backwards' toward L again)?
