follow up phone call

[Mario T.]

i'll speak with the seller the first time and they decide they don't want to sell the property at the time.  few weeks past and i call them to follow up. 

after i ask about the property and see if they've changed their mind that's all i wanted to know, but feel like it's kind of rude to have a few seconds conversation.  what else can i ask or talk about?

what in the world do we talk about to keep it from being awkward?

thanks
