Facebook’s Need for a Sympathy button

There is an awkwardness to some Facebook posts about people or pets dying or other really bad news. Sometimes I see people post about the death of their grandmother, for instance, and 15 people LIKE the post. Is that appropriate? I don’t know whether to LIKE or UNLIKE. Hey Sam, I like that your grandmother just died. Maybe there needs to be a SYMPATHY button to cut down on people LIKING death and destruction. Maybe they really didn’t care much for the grandmother?
