the first two lines are clear in their meaning. But it's the last two line that I like best. The others are pretty random which well matches the randomness of observations........stan

filled with just the right amount of mystery and images. Works on a subconscious level, very hard to achieve. Nicely done.

(only comment would be to replace "third" with "following," or "after" or some variation rather than numbering the sequence of events so specifically...somehow too concrete)

beauty of youth a kid
then learning with a sibling
a lady of substance
a wife
later an everlasting memory
where do I belong to like!
as of now
what says the mirror
still majestic

great use of literary devices as usually is in your poems to create the perspective the Protagonist intended as in this poem...i liked the visual of looking from the corner of a "curious" eye to recount the moments as they passed by....i would agree with Eumolpus that numbering the events could be avoided...i believe so because although these are pleasant bygone events when your title mentions the word "messy" a disorderliness is expected...many readers would probably relate to this poem because one does reminisce about such memories and figuratively try to get them organized to clear the mess...even though the reality is that one cannot reverse them....in short verses you have created the bigger picture.....

well done but one tongue twister 2nd stanza 2nd line leaves of the color of how about just leaves the color of ?

@UR FLOW like
ALL OVER NIAGARA
i was the safe custodian earlier
as words
in liquid form
hammered the waters
till sounds were heard
which did shatter
the world of all viewing
NIAGARA as it falls!!
ur mind is a Thesaurus
mine not at all
guess work of words
which come and call
and
loved by all
It's coming from
LOVEDLY
after all

A peek at others yet I assume that you remained within your self.
The fourth line needs some attention and as I am not sure if this is a set form I wont say about a change and leave this to you :-
Then, it was a flock of falling unwillingly leaves,
leaves of the colour of linnet wings,
You have repeated Leaves and of.
Both can be replaced with your words.
Take care, and lovely to walk with you here,
Yours, Ian x
