Sitting with people that are involved in sin

I obey and respect my mother as Allah commands, however my mother is angry with me because she wants me to talk to her more, but this is difficult for me as she is always watching haraam shows on TV. I talk to her when she isn't watching TV. I assume it is not permissible to sit and talk to someone whilst they are watching haram things. Could you please clarify if this is halaal? If it is then I will do this so that my mother does not remain angry with me.
