Imagine: You receive an e-mail from the friend of a friend, asking if he might stay with you for a week or so while visiting your town on business. "Of course," you say, but caution him that your home can be a bit hectic: you have two children and two dogs. Your friend's friend says he understands, and is grateful for your hospitality.
Now imagine your guest arrives and within days, informs you that his religion precludes him from living with dogs: you will have to remove yours from your home, at least for the duration of his stay. What do you do?
If you're like most people, most likely you will suggest that he might more comfortable at a hotel. You may offer to ask other friends of yours if he might stay with them. What you are not likely to do is take the dogs to a kennel, or, should he extend his visit, give them away.
