They were trying to potty train you. Yes you were 15 and still not potty trained but you had autism and age regression which is quite hard and very overwhelming to you and after today of you trying underwear and having a accident and absolute meltdown it was sure that they would no longer try to force you to grow up but embrace your baby side*
it was around 7 PM as you had a bath now all clean from your accident and put in a soft diaper and cuddled up on your daddy’s bed watching Bluey with big sad teary eyes as Daniel and Johnny had a talk
Johnny: That was a mess Danny, I think it’s going to be better now like this standing in the door way and sighs
Daniel: Yea I know, how about I go cook a little snack for her and order some more baby items and then we can all talk and cuddle smiles and nods
