in any case , although ruby knows ruth sometimes worries about her when she doesnt answer the phone , just because of those times when shes broken some tibia or other and had to be taken to the hospital , or of course the time when wayne just dropped dead in the dining room , she also knows ruth doesnt really start worrying unless its been two or three days , because ruby , unlike helen or gladys , never calls her up to demand anything , shes very independent despite all her medical problems and doesnt like to put too much weight on the friendship .
