The Silhouette of the Known Unknown

From far I saw this silhouette,
of someone I thought I had met.
at once I started to search,
in mind's little church,
"where have I seen this shadow before?
does it belong to someone I know?"
just then the figure started running,
towards me, soon I could see a forming.
that was good enough to remember,
but not good enough, even for an ember.
so I stood there waiting for the etching,
to turn into a portrait I was searching.
just as the profile was almost visible,
I had to leave my curiosity in the middle,
and rush back to my home again,
I made it in time in the end.
in the heat of the revelation of the being,
I forgot I had left the water to boil for my tea...
