Matriculate is not the same as graduate, and in any event I was including as a Boilermaker anyone who loyally follows our hoops and football teams despite all the disappointments over the years. So chances are good OP is a Boilermaker.
I will take your advice, however, and chastise him if I see him being rude to you (be warned, OP).
I completely agree with you re stigmatizing people about mental health issues. However, in Biden's case I think it is fair since it is obvious he should not be running for any elective office, especially the highest. I really wish his handlers would face up to that and have him drop out -- and actually won't be surprised if they do that in the coming weeks.
