Orach Chaim (225:1)
הרואה את חבירו לאחר שלשים יום אומר שהחיינו ואחר י"ב חודש מברך מחיה המתים והוא שחביב עליו הרבה ושמח בראייתו:
“One who sees his friend whom he hasn’t seen for 30 days says “Shehechiyanu”, and (if he hasn’t seen his friend) for 12 months, he blesses “Mechayei Hameisim” (who resurrects the dead). And this is (talking about) when it is his close friend and he is happy to see him.”
Nowadays, since people will know almost immediately if his friend has died, is this halacha still applicable? What if he has talked to his friend over the phone, or with text messaging during the year?
What do modern Poskim say about this?
