Welcome back professor and im good, i had okay break , but now am in school again. Classes are long now since i go all day for 7 hours then instead of 4. I miss the 4 hours and I want to go home cause classes are hard and make my head hurt. Is that good that my head hurts for the these reasons? I do not know of any answers but if i need help i let you know. Thank you and everyone who come here and help people with the math works. I gladly appreciate the work you people put in to. My mom always said that i never was normal like you people, that I am not from here. Grow up to be big now i do believe it. I am not human, Im not robot or machine. I am something else but not human for sure unlike you other humans who i study when i walk by or talk to. Thank you for teaching me how to be like human.
