One of my daughter-in-laws has taken a job with a hospice organization as a grief counselor. One of the job requirements was a master's degree in social welfare. There was a period of training for the job to learn customs of different cultures in the US so that the grief counselor would not offend someone. The different culture customs that she has come into contact with are very diverse and extremely divergent from each other. It is a very difficult to tactfully procede even when you know the religion of the family and the dying person. Flowers and quilts are welcomed by some and refused by others. Solitude are sought by some and keening by others. There is nothing that can be presumed to be welcomed or to be refused by a grieving family.
