I may not understand what the problem is, but my sister is not a liar. If she says she has a medical problem and needs my help to relieve that pain, what kind of a brother would I be if I said no?
Our parents had two sets of twins: two boys, and then two girls. Because my brother and I were older, friends and family always thought we were mean to our sisters and bullying them, but in reality that couldn't be further from the truth.
