My really close friend committed suicide on Sunday night and his funeral is tomorrow. Its a closed casket so I was wondering what I should do about bringing something that Id like to bury with him. Ive never had to do this so is it appropriate if I enlarged a pic of him and I and placed it next to the casket? Sorry if this sounds dumb but I just want to do it since we were childhood friends.

Also, are white flowers appropriate on a day like that?
