to see if there is a day coming up that Wee will be out for a doctor's appointment or anything...they are lining up crisis intervention prevention and de-escalation training for ALL of Wee's teachers and paras.
1) they're looking at some long overdue training
2) he called in advance
3) he's looking for a time when Wee is legitimately out of school vs. sending him home illegally or letting him sink with unfamiliar faces.
