The trembling tower

There’s one thing I wish to know…
Nay, not wish but instead must
know if you are a friend or foe.
Are you someone I could trust?

Can I let you past my crust
to places others cannot go
for fear of their wanton, selfish lust?

Are you someone I can show
my fragile, wounded heart of rust
who won’t add, again, unto my woe –
are you someone I could trust?
