PLEASE HELP!

I'm trying to send this poem to my uncle, who is an English teacher, he has left, and I might never see him again, please help me add a few lines, of replace some of the words, because I think this poem looks so simple, also if I had any grammer mistakes, please tell me.
and tell me what do u think of it :)


a paper and a pen which writes in blue.

I hold it and think.
what should I do?

write about love?friends? of write about you?

the last thought was the best.
but where do I start?
I had no clue.

thoughts are many.
but words are few.

so I remembered the old days.
it was not a long time ago.

how u came to our house.
and how did u go.

I remember everything.
your face, smile, clothes, and even your shoe!

everything u zei was interesting.
and so funny too!

and within a few days only.
I realized
u are the best relative I've ever knew.

don't u believe me? I swear! it's true!
