How do I tell my Mother it's ok to slow down and don't worry about who gets what - right after my Father's death?

I just read an email from my mom – she was telling my dad’s specific requests for certain items. Paintings, the grandfather clocks, the other clocks – mostly antiques. You get the idea. Truthfully, I don’t want these things, right now…and with my mind in the state that it currently is, I’m not sure I ever want them, they won’t bring him back and that is the only thing I want, right now.

She’s on fast forward, all the time, since he passed away this past weekend. I would be afraid to take anything from the house, anyway. I know she’s not thinking clearly, right now -but she is insisting that we do this, very soon.
