No battery

My sis called up just now and halfway in the middle of our conversation, the line got scratchy and it went dead; just as i was telling her how much to pay me, knn. Aighhhh.... more like her cordless phone battery gone dead, as usual. Cant understand why she never bothers to get it changed. Now, i've gotta wait for her to recharge it, then only can call her again. She says lazy to go and get new ones wohhh. So troublesome!!! Yerrrrr!!!
