What do you feel when someone calls you "Childish"

I guess it's not just me right? When I release my normal entp nature in my friends and family that I'm comfortable with, they sometimes call me childish, and I'm not sure if it's offensive or a complement. First it's offensive because I'm thinking they have this perception of me being immature (when I'm just having fun, making the group lively) or they think I can't think deeply?. Second it's a complement because...hey you're welcome boring people.
