I'm going to pressure some friends to come to another friend's funeral.
Why would you pressure them to attend the funeral?
I don't even want to tell you. The funeral is tomorrow
I understand that you may need the support from your friends at the funeral. However, you shouldn't force them or make them feel pressured to go.  You should talk to them about how you feel, they may not be aware of how much their absence at the funeral will bother you.
Whatever, I'll try to talk them later.
I'm glad you'll try talking to them about it. It's better than forcing them to go.
