Minimus: My mom is very ill and the congregation has been very good to her. I think she may be in a hospital soon or elsewhere. I think I will be seeing some elders who might try to love bomb me.
If I knew the person calling I would act happy and very surprised they were calling. Thank them for doing so and start asking about them, their family etc. In my case it has thrown them off course, then "Oh dear, I really have to go. It's been great catching up with you. Take care, say "hi" to the Suzie and kids."
If they sneak in a request to visit, I just say "now isn't a good time. I'll let you know."
Best thoughts to you and your mom.
