Ohhh....your sister must have been in pain, teeth pain is always painful, the last time I experienced this situation, I couldn't chew anything except eating just soup, I mean ordinary soup, so sad. Your sister could laugh well you joke about the sunsbun, it was really painful I must say. The road to your university is very calm and I like it because at least motor accident is not really much. You're right, you'll surely remember the time you stay away at night just to study but before then, work hard. All the best of luck...🤗
