when you're excited about a new semester starting and you buy all new clean journals, new supplies, you tell yourself that "this semester is going to be different", and then as you get further into the semester that high wears away, and you're back into you're old habits.
"Sis, this semester I will have all A's. Let's hope this new semester high last all semester."
"I'm not feeling this semester. I'm over the new semester high."
