eating in convo

While eating in convo, I watched a couple of people eat their meals. As I watched one person, I noticed that they always took a sip of their drink after every bite. It wasn't a big sip, it was just a very little sip. I also saw that the person would always lean towards the table when they went to take a bite. The person's chewing was kind of weird. It looked as if their mouth was moving side to side. And finally, I noticed that for some reason they were eating their ice cream with a fork. That suprised me a bit.
