Adjective. An evolved quality of showing thoughtfulness towards someone you care about by anticipating their future needs and proactively providing for those needs. Being merely “considerate” can include holding the door open for a stranger, passing the salt, cleaning up after yourself so the next person can use the table, helping an old lady crossing the street you are also crossing. Being “preconsiderate” can include packing a gift of sunscreen, maps, or an umbrella; setting up a college fund; giving a reservation to a spa, fine dinner, or concert.
