Question. Poem by Neil Gray

I followed her too work this morning
just to make sure she
got there o.k.

Then I picked her up at lunch
so she'd have nobody
disturbing her
while she ate.

The I walked her too the pub
for her evening drink
where she joked and laughed
with her friends.

Then I made sure she got home o.k.
in her drunken state
as she caught the last bus
and I sat
2 seats behind.

Now tell me.

Am I in love?

Or am I a stalker?
