Yep, its the same confussion when we're all at my mother's house and the phone rings. If they ask to speak to Levi, the next question is "which one?" Middle names don't help since they all have the same one. The same thing if we see someone we haven't seen for awhile, they always ask, "So how's Levi?". I've quit asking which one and just start with oldest and work my way down. I figure eventually I'll get to the right one.
