For initial appts., I do request that initial contact be made via PM, email, and/or thru my website.  For already established friends, I do not mind if you call me but still suggest that you first try with an email or PM as I respond in a more timely manner to those requests, for the most part.  If you are calling me and the number is blocked or if I do not recognize the number, I will not answer so PLEASE leave a message indicating IF and WHEN I may return your call or else I will NOT do so in order to protect your privacy.  Upon receipt of your message, I will promptly acknowledge your call with a text, voice SMS message and/or a phone call at my earliest convenience.
