The daughter, 28, had been spending time at home while also grading papers for the end of the semester. OP complains that the daughter seems too busy to help out around the house or to even be home for a long period of time.
Last week, OP asked his daughter to exchange a sweater, a gift he'd purchased for his younger daughter that she ended up already having. The older daughter said no because she is too busy grading papers. OP does not want to do it because he works out of the house (while the daughter works from her computer), and will be too tired after work.
Later, OP needed his daughter to pick up a gift for his mother that he'd purchased online, but she once again said she was too busy and refused. OP said he was too busy, so the daughter retorted by saying it'd be done on her own time. OP said she can stay somewhere else for Christmas, to which the daughter said she'd just spend the holiday with her girlfriend's family.
OP admits that he and his younger daughter frequent the sub, so he figured he'd ask the community. His younger daughter is also really mad about the situation.
