"These things happen"
No shit sherlock 
Saw a friend a few days ago, she asked how things had been since losing a close family member. I told her and this was her reply. AIBU to think that it's the sort of thing you just don't say to someone who's grieving and that it shows a complete lack of empathy? Death is a part of life, everyone knows that. But comments like that aren't in the least bit helpful.
