Vicki, I am now 73! If you ever had the oppotunity to talk to my youngest daughter Kate who is now 41 and ask her, 'what was the best holiday you have ever had'....she would say without hesitation, the month she and her dad had in Hawaii in 2009. We shared not only a room but, a few nights, the same bed. The very thought that anything about this was 'sinister' to any regular father, frankly Vicki is abhorent.
Vicki, the fact that you bring this up probably says more about you than it does about the potential guest.
I prefer not to see evil around every corner, you are new to hosting so I understand that you are apprehensive about who you allow into your home but Vicki, I can talk from experience! I am a Superhost with 180 guests who have entered my life, 140 of them through Airbnb.....
There is not one I would not gladly want to see walk up my driveway and into my life again.
Guests are going to be different and maybe have a different set of values to those you may hold true to yourself, but you will find, inviting the world into your house can be the most rewarding thing you will ever do in life.
Invite this guest with his mother, he has told you his position and you can be sure....he won't be sharing your room with a local 'callgirl'!
Cheers.....Rob
