I prefer that you write me. I usually don't take calls, because I don't want to expose my "secret" phone in my daily life. 

Write me in a respectful and nice Tongue.

Give me a short and nice presentation of your self and and a short description of what you want and when you want to meet in your first contact.

Familiarize yourself with my concept, my limits, my time schedule and my requirements before you write.

Remember that I always have to see a picture before we meet. I will of course return a picture of me.

Respect my time. I'm not here to entertain you by endless chatting before we know each other.
