3) I'd tell her to go to school because waiting that one year to start school at age 6 as it is common here will set her up for a lifetime of disappointment in education. My parents wanted to send me early, but I put it off. I don't know if going early would have changed things, but I'd try to explain to my bb self that starting school early was full of benefits I didn't realize at that age.

2) I am pretty unforgiving about deception, I don't give my trust easily and you don't get it back if you trample all over it. (Example: when Emily and JJ came back on CM I was shocked how fast everyone forgave their lie. I can acknowledge Hotch's intentions, but I'd never be able to trust them again.)
That said, I do think it can be somewhat justifiable if you are protecting yourself/someone from someone else. (Like I said I get why Hotch did it, and that's easier to accept than if he'd done it for personal gain or something. But the consequence would be the same, I don't think you can re-build trust.

I can't pretend I'd never lie, no matter to whom. I've lied about my mental health, about my feelings to family and friends, those closest to me. I wasn't ready to talk to anyone about it or to get anyone else involved.
