Mleigh - if he can't own up to doing a fly-by w/the drone, I don't see him admitting to anything more serious.
But, I think it was smart to ask for how many tardies your son has had this year and to determine when was he signed in on those late arrival dates. 2 hours late?!? Mine is not an oversleeper. He is too busy trying to outrun the Grim Reaper that haunts him! He burns the candle at both ends.
I only have experience with my MLCer, but it's up close and personal and I can certainly see how people could believe they are on drugs when that fog is so deep and that confusion is massive. It's a sight to see. Unless this friend has seen it, I wouldn't assume. But, to people who don't know what's going on, I can totally see why they would assume that.
