Lip liner - They have a use?

I never under stood lip liners- We have lip stick and gloss!!!
However this pic explains it all, and yes I tried it.
Its hard to trace your lips with lipstick so liners when sharpened can give you a very neat job.
No smudges or patched over foundations any more!
My extra tip is to defs place gloss over the top to plump your lips up, so they are nice and juicy
