an old flame left my close fire door ajar

there is a bit of poetic licence going on here… the door was actually jammed wide open. close is a funny word. is it more than one word, or a single word with different pronunciations and meanings? it juxtaposes both with ‘open’ and ‘distant’ and lends a tender ambiguity to the line. and there the repeated idea of flame and fire, doubling down on warmth. i also like the way it feels to say this line, almost mono-sylabbic, little phonetic bubbles.
