I am not a doctor but, (as a child) I used to play doctor with the girl next door.... But...If I was a shrink...
"B" is anal retentive and needs laxatives and about 50mg (per hour) of Thorazin so he can sit and drool in the corner. "R" needs to start drinking again so that when "G" comes back, "B" will appreciate "G" more. Hopefully (in a couple of weeks and lots of BM's) he will "mellow out" and let "D" (who he is secretly in love with) actually enjoy the gigs.
