What did Barak Obama do to honor the life of the woman who raised him?

I believe it's been one week since his grandmother died and I don't believe I've heard one thing about a funeral, a wake, a service or anything that he has done or attended in remembrance of this woman who he says meant so much to him. Shockingly he has had the chance to take the weekend off in Chicago with his wife and is going today to check out the new digs on PA Avenue. So, does anyone else think it strange that the man had to leave his campaign for two days in the week before the campaign to visit her but has literally done nothing except mention her in a campaign speech after she ped. Doesn't say much for his character in my opinion.
