如何写A letter to my parent

dear mom and dad:
how are you doing recently? i am your beloved son.
today, i wanna write a letter to you. and i know it would make you happy.
as my parents, you have given all your love and care to me . and i am very grateful for that.
when i was a toddler and walk my first step , you,mom and dad, waiting for me on the other end opening your arms expectantly
when came my first school day, you held my trembling little hand and reasuring me that you would come to pick me up as soon as you get off work
when i fumbled my exam, all i got from you is encouragement and reasuring smiles.
..............................................................................................
i know just a letter is nothing compared with your love.but i think you deserve it anyway
i have a word hidden in deep heart for a long time: i love you, dad.mum
with all my respect and gratefullness
