PLEASE HELP!

I'm trying to send this poem to my uncle, who is an English teacher, please help add a few lines, 또는 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? 또는 write about you?

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

thoughts r many
but words r few

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

how 당신 came to our house
and how did 당신 go

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

everything 당신 said was interesting
and so funny too!

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

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