Interesting that Tea is away somewhere tropical for a vacation when West turns 18. So David has the kids and is in NY, and Gillian is ‘missing’ so she could very well have been in NY to share celebrations or she might still be there! And the interview David does today is radio so it makes sense that he’ll call in from NY. (There would be no reason for him to be in LA when West just turned 18 and is getting ready for final exams! From what I’ve seen, either he or Tea are always in NY w/kids.)
