Wits must he have | who wanders wide, But all is easy at home; At the witless man | the wise shall wink When among such men he sits. (Hávamál 5, Bellows trans.)

The All-Father states here that when one would wander, meet with strangers,and attempt to mingle with others, there is necessitated a viable wit or one can become the laughing-stock of an assembly. It is easier to speak of simplicity outside of the hearth than to experience it first-hand.
