Second Life interactions go poof?!?

Yeah, I totally have been so adroit in my 1st life that I haven't had time for my 2nd. Well, I have free time now, the past weeks I have been super excited about scheduling! Hoping to double up on sciences next year and get Trig/Stats in, if I can get my grades to 3.5 GPA I will be taking College Pre-Calc instead of Trig/Stats
