Wow, I did wonder where you would go with this poem from the title, I thought it would be really deep and about alarm bells of emotions and life and danger etc.
However, what I find is literally more simple, the sirens of emergency teams passing by, and you have turned that moment into something deeper, which we can relate to. I often wonder some of these things myself, when I hear or see an ambulance or fire engine, your imagination can lead you astray, and you very rarely get to know the outcome of the situation.
I like how you add in a part of your own personality here:
I worry as a young woman who can't save the night
- to me this shows care, and deep hearted passion of kindness, just wanting all to be well and safe for everyone.
I like when something simple is turned out to be beautiful and quite touching, yet nothing much has happened within the poem itself.
