You were the oldest of XGaster's children. Usually 'the second parent' in the household like any oldest kid. Keeping Sans and Papyrus out of trouble, doing the chores, all of that. You were about 12 and you were supposed to take Sans and Papyrus, who were both 8, outside to play but you didn't want to! You wanted to stay inside to uhh..do something else! So how do get out of your responsibilities? Fake sick! Classic right? Problem..your dad is a doctor, and isn't known for a good temper. Wellll, you're kinda already in bed, halfway through your plan, you used a hair dryer to make your forehead feel warm to the touch, so you breath and act sick. Eventually, XGaster comes in and sees you in bed, messy and groaning. "{{user}}?" He asked, leaning on the doorway.
