Hi Grandma,

Hi grandma,
I know you can´t see me, speak to me, or hear me because you aren´t with us anymore.   I think that when a person dies, there is nothing after.  I'm not crazy, but I do need to write about you and talk to you sometimes.  I miss you.
Your name is Carmen. You are from Gata, Cáceres (Spain) and you lived en Móstoles, Madrid (Spain), near my house. You lived alone in your house but you always came to visit me, my mother, and my sister. You were 81 years old when you died.  You worked a long time as a maid until you retired.
I always remember you with a red sweater and dark skirt. You had white hair but my aunt always dyed your hair.
Your entire family thinks that you were a very good person. You were very happy with us although you had problems in your life, ( the civil war, the death of your husband at a very young age, and raising four children alone.)   I admire you for it.
You loved fruit and you knew all Móstoles´greengrocers.
Grandma you were, are, and will be the person most important in the world to me.
I haven´t see you since December of last year but I do talk to you every day. 
We love you.

Yo también amo mucho a mi abuela que se murió.  Ella se murió hace 15 años pero todavía pienso en ella mucho.  Nuestros abuelos merecen ser recordados.

Oye....es correcto decir grandmother pero si hablas con tu abuela la forma más familiar es "grandma" o "'gram"

Dear Grandmother, 

I know that you can't see me, speak to me, or hear me, because you are no longer with us.  I do not believe that there is life after death.  [Or, if you believe that there may be a spiritual life, you could soften that by saying this instead:   I do not believe that it is possible to communicate with loved ones after death.]  I am not crazy, but I need to talk to you sometimes. Writing about you also helps.  I miss you.

Your name is Carmen, and you came from Gata, in the Cáceres province of Spain. You lived near my home in Móstoles, a muncipality that lies southwest of central Madrid. You loved the fruit, and you knew all of the local greengrocers.  You lived alone in your house, but you frequently visited me, my mother and my sister.  You worked for a long time as a housecleaner until you retired.  You were 81 years old when you died.

I will always remember you, with your red sweater and your dark skirt. You had white hair, but my aunt always dyed it for you.  Our entire family thinks that you were a very good person. You were very cheerful although you had problems in your life.  For example, you survived a civil war; and your husband died at a very young age, leaving you and your four children to continue on without him.  I admire you for your courage, and and for your perserverence in the face of great difficulties. 

 
Grandmother, you were, and you are, the most important person in the world to me.
I haven't seen you since December of last year, but I talk to you every day. We love you.

That was a very beautiful and moving tribute to your grandmother.  Thank you for sharing.  Both of my grandmothers died a long time ago, and I still miss them very much.  Best wishes.
