Just read this article about how barbershops are measuring people's blood pressure and pointing them in the right direction if they measure high. Way to meet people where they're at! I read an article a couple years ago about how a barber took classes because he was also a therapist. People would talk to him while he cut their hair, and he wanted to make sure he gave them the right advice.
I'm just entering the world of grief and bereavement counseling, but the biggest thing I've learned is nothing you say is going to be ultimately helpful. You can't feel what someone else is feeling. Even if you've lost the same person, grief is tricky because it means something else to each one of us. The best thing to do is just listen.
