Mothers...Would you allow your adult son to crawl in bed with you for the night?

While at lunch today, I overheard a waitress admitting that her 26 y/o son drives over to her house just to crawl in bed with her so he can spend the night. Most of her coworkers were teasing her about it & she refused to feel bad about allowing him to do so. She has 2 sons & the other one sleeps in his own bed. In my family, once you start going to school, you sleep in your own bed!!! What you think???
