Karen and her family were making their way back to the US from their vacation in Mexico. They were in line and got out at the stop to use the bathroom. When they returned to their black car they noticed that the door was locked. Their dog had stepped on the lock and the keys were in the truck so they couldn't get in. They were trying their best to get their dog to press down on it again. Karen's mom then holds another dog and her dog gets angry and jumps at the window. Because of that the dog presses on the door window button and opens the window so they can get in.
