premise: Now I ' m old , tired , and just do n't have the energy for long drawn out fights . After trying several different ideas , such as having him clean the bathroom , do seat - lifting repetitions , and writing sentences to no avail , I solved the problem by leaving the seat up when I ' m done . Because I do n't actually care if he lifts the seat before he pees , I just do n't want to sit in pee . Why does the writer not want to sit in pee ?
hypothesis: Because they are tired .
