That sounds glorious! All it takes is one day like that every so often and it gives you happy memories to cling to while your 3 year old has a total tantrum melt-down during a Skype call with your grandparents or when your teenager gets caught skipping school (both of which happened this week for me). I'm glad you had such a successful and satisfying day of adulting. You deserve lots of them- way more than you will likely ever get.
