Recently my cousin passed away, while he was in Nepal and his wife was living  abroad..My cousin family were looking for a rite time to pass that message to her. but she found out through face book where people had posted condolences. & which came as shock and also much more painful way to find out about your husband deaths,so it is very wise to think before you write anything on anyone face book. it could be offensive and painful, and also tagging pictures.. people need to respect people privacy.
