Summer is where mostly everyone wants to stay outside rather than inside the house. Especially for those who live in the northern part where Summer is only a few months we normally spend more of our time outside the house to take advantage of the warm weather before winter comes.
So, when we have parties or just simple family gathering, we choose to have them outside the house. In our patios, decks or in a big tent where everyone is outside. And of course we also use our patio dishes as we don't use them that often.
