Z. has to start packing for college soon. I do what I can to help him along, packing a set of stand-by medication to keep in his dorm room in case he has diarrhea/vomiting/runny nose/fever/cramps/sore throat when the college clinic is closed.
The rest is up to him. I restrain myself from telling him what to pack. I ask him to enroll himself in the uni health insurance plan. He needs to do the pre-registration tasks on his own.; the housing application; registering for orientation etc etc etc.
All this a part of the transition & the letting go.
Both for him and for me.
