Fair enough.

I'd still personally consider it extremely weird and suspect even after two years, something like a teacher who started dating a former student after they turned 18. Maybe not technically "unethical," but I think it speaks volumes about someone that they'd date a person they met in a situation of such power differential. I'd think there was either something predatory or over-enmeshed/rescuing in their personality.

So, yeah, if I felt the need to ask I just wouldn't see the T at all.

But that's just my opinion. To each their own.
