I take since only a Mom is mentioned, there is no Dad.
Moms are the most protective and worriesome of either of the two parents in life.
I have been the first to go to college in my total family and the only one to join a GLO. Neither were sure about this and I am sure worried.
Well, I left a Fraternity and started a local that later affiliated with a major Fraternity.
They would visit and got to know the Guys (Brothers) and were warmly welcomed and accepted by them.
The main problem may be the unkmow for Mom. Her little boy is on his own and is really worried about you.
Just try to not prove her wrong!
