I mentioned to a friend the other day that me and my sister (3 years older) had shared a room growing up and that my brother (7 years younger) had slept in an alcove area of my parent's room as there were only two bedrooms. After my sister left home he shared with me. My friend was shocked about him being in my parent's room (which I understand is unusual) but said she thought it was unusual that me and my sister shared a room when we were teengers and that she didn't think that really happened anymore. She's bu, isn't she?
