I keep hearing stories from my friends about how they travel to Europe for just a few weeks and end up falling in love with someone while there, after being single in their hometown for a long time and not being able to meet anyone they would care for, for years. I also hear about how the locals in my town (San Francisco) fall for people who come to the city for a short visit or business. I have also personally experienced having strong feelings toward a woman who was visiting in town on two separate occasions.
