Xander was insistent on getting mint ice cream. Brian got cake batter swirl in a cone in a cup, and asked if Xander wanted to share but Xander only wanted mint. When they got their ice creams, and Xander tried a little of Brian's, the conversation went a little something like this:
Xander:(holding Brian's cone) Ooh! That's good. I wish I got the cake batter cake.
Brian: Well, would you like to share a little of mine?
Xander: How about you can eat my ice cream, and I will just eat this one.
Brian: Uh... no. You said you wanted mint ice cream, and I don't like mint.
Xander: How about I eat the cone and you have the cup. (the cup had about one more bite of ice cream in it)
So Brian suggested a flavor for them to share, but Xander had his mind set on a different flavor, then decided that he liked Brian's better, and tried to finagle his way into trading. Who does that sound like? cough*Kelley*cough
