I have no problem starting conversations about anything, or anyone.
Usual conversation starters for me are based around a diservice, or something I am not satisfyed with. For example I will be talking to a person, and when they ask 'So what were you doing before I called' I always say something like 'I was watching TV, have you ever seen this comercial, it is so stupid yada yada blargh, have you seen it' and then the conversation sorta migrates.
I also am very direct 'So, I heard you packed on a few pounds since we last saw eachother, loose weight fatty' That never works.
THE END!
