Congratulations sonew123!!!
They are very excited about seeing New York! Pertinant details . . . let's see; the girl just broke up with her boyfriend and misses her sister who just got married - expect tears. The boy is taking his 1st girlfriend on their 1st REAL date - expect much texting . . . the girl is the better builder / animal handler, the boy the better cleaner. No special diet restrictions other than don't give the girl energy drinks you will regret it! Regardless of what they may tell you neither is allowed to drink, smoke or drive. That should do it, they will arrive via air in seperate live animal crates, just return when you run out of food!
