Tip #1: Chikys!
Tip #6: Find different ways to sit. Feet on the floor, feet on your backpack feet under your butt. Knees on the seat in front of you, head on the seat in front of you, head on the window, head on your own seat, head on your husband's shoulder, head on your sweatshirt, head under your sweatshirt.
Tip #7: Look for cows, pigs, chickens, ducks, donkeys, and other animals that you recognize. I get really excited when I see cows because I grew up on a dairy farm. Except here they have Brahmen cows, which I hope to post pictures of soon. Hubs gets tired of me saying, "Look, there's a cow!"
Tip #8: Read... only when the bus is stopped.
Tip #9: Try to read the Spanish signs and billboards.
Tip #10: If you feel sick, try to fall asleep.
Keep using these tips until you have reached your destination.
