Lonely child

With our daughter and her son newly moved out, we are left with only one child at home , our 3 and a half year old Freya, it all seems a bit quiet now and her playmate / arch enemy , our grandson has gone. She has bothered us all day to play with her , I am filled with guilt at having her so long after the others and long to provide her with a new playmate...... but oh we have a spare room.. and thats fabulous ! she was standing in said spare room window, we had been watching the rain and shouting at the chickens in the garden, who always provide a bit of light relief
