How to get involved in feelings maintaining Equanimity?

Sir, when I talk to my wife over phone (maintaining equanimity) she suddenly recognize that either i am not in a mood to talk, and its obvious becuase even I know that its impossible to remain equanimous and get involved in the conversation whole heartedly, I am not sure I am making myself clear. My question is lets say I often make jokes on phone and laugh a lot when I talk to my friend, but I find these things stupid while trying to maintain Equanimity. Kindly explain is it possible to do both the things?
