we have a big band with two sub bands im the bassist for one sub band. the other girl won't talk to me, shows up an hour late without telling me, doesn't want to communicate about parts and weeks etc. When nobody shows up, or the the bass part isn't good cause she won't practice or try to get the songs from me or the website, we r both in trouble. How do i cooperate with someone who won't talk or respond to what I send her???????
