How I Could I Deal With This If These 2 Teams Play Each Other In The Playoffs?

Ok I live in Atlanta and im surrounded by Falcons Fans in my family. Of course I root for the Falcons because I live in Atlanta. But also im a N.Y. Giants Fan I absolutely love the Giants im a die hard Giants Fan. Like if they play each other how do I deal with it I know some of my family is going to root for the Falcons because they are the hometeam and they will be saying the Falcons are going to win. But how do I stay away from that when they play? Its very likely that they will be playing in the playoffs. Its obvious they will want to know who im going to be rooting for I like the Falcons they are the hometeam but it will be really hard for me to root against the Giants. How do I deal with this or how should I deal with this?
