I know a woman in Spain which is much older than me, I respect her, however our relationship is very informal. Yes, sí la trato de usted, but otherwise our relationship is very informal and friendly - like my grandmother I could say. How should I start letter to her? I don't want to start (say her name is Carmen Jose - false name):
because it sounds very formal and reserved for our relationship (yes she is 80, but she is Spanish! Very friendly). I also don't want to start
because if I look in the dictionary, this is what lovers use, too sweet, and I don't want anything close to that...
So please, how should I start (and also end) the letter? I only found these two phrases which seem to be the opposite extremes!! I need something in between.
How would you write with your grandma?
