Overprotective Mothers

There is a time when you need to let your baby grow up! I'm at the work (dentist), and there is a 20 year old here getting her wisdom teeth extracted. At TWENTY YEARS OLD you should be able to fill out the check in form yourself! This mother has called in to the office no less than five times getting ready for this appointment. I would think that a twenty year old would be old enough to set up her own appointment.
This happens even more often with adult sons. I've had more than one mother call in to make appointments for the children-the "children" being over 30 years old!! One mother kept going back into the operatory when her 25 year old son was having his teeth extracted.
Don't these mothers realize that they are just making their kids weaker by not letting them deal with the everyday tasks of life?
It kind of makes me want to let Night fly from the nest now... He's three. It's time to toughen up.
