However, suppose upon boarding such transportation you sit next to someone else, then later a lot of people disembark. Would it be considered best to stay where you are, or move to a seat with no neighbors?
Whoooaaa! Slow down their buddy! If you get into such a position, you have already made the wrong choices.
Firstly, when you have to sit next to somebody, it is customary to offer them a mint, or failing that, a business card, as a show of good will. This will ease future relations. Now that social contact has been made, try complementing them on their confidence in appearing in public looking as they do. They are a hero to be able to walk around with their head up high, what with a face like that! This is called flattery, and will convince them that you enjoy their company. Eventually they will pretend to ignore your comments, this is because your flattery has attracted sexual desire, and they feel too shy to return conversation. You are on the right track! Now is when you should try to nibble their ear, just a little, only using your lips, no teeth. This show of acceptance will leave them feeling both in bliss and awe of your kindness. In order to attempt to return this kindness, they will often stand up and either move to another seat, or just stand for the rest of the trip, to ensure you have all the seat room you need. They care for you, and want to see you happy, so are willing to sacrifice their seat for you.
You can now enjoy the entire seat to yourself!
And now you know.
