My sibling, don't know how to call him/her, psychopath, or sociopath or egocentric? He/she does not give a damn about me. Today he/she was washing her hand at the sink where dishes are usually wash, with soak, and at the same time, my cup of milk was there. He/she didn't even care for the cup of milk and washed her hand. Nasty, I know. All the soapy water splashing around and drops falling in my cup. Really hate him/her. Why don't people care about others? Hell, I care for him/her every time and help him/her whenever help is needed, nut now I'm really thinking hard about...should I care and help others who don't give a damn about me?
