you know what she will be doing the whole time during the trip? barfing!
Last time I went Ringo puked 3 times And I was in Johanna's car. The first time we went Ringo didn't puke at all. I think he was trying to embarrass me Just Kidding. Maybe you can tell him you'll have lotsa Paper towels and Wetones to clean it up just in case. Do you think that would work?
