I do have some suggestions:
1 paragraph
You can use a better verb or phrase than "goes by", for example, "pop out"? Choose a verb to express your surprise.
3 paragraph
The scenery/description is not vivid enough, too bland for me.
4 paragraph
The word "we" is too sudden. I suppose you refer to the "who" in the 1 paragraph? There is not enough reference of the person or people you ask for response? Maybe add a paragraph for them?
"Blue" and "sad" mean similar feelings. " blue" is a better word than "sad" though if you want to get rid of one of them.
I do like your word choices such as recollect and uneasily hesitate, which evoke feelings out of me when I read them.
