Do Unto Others
Do unto others as you would have them do unto you. Following this guideline, I would try to determine the strangers' needs and assist them in meeting those needs. If they are hungry, feed them, etc. Providing strangers with a caring, sincere attitude on your part can uplift [his/her] outlook on life. I currently contribute to several charities that provide shelter, food, clothes, and other items to assist [people in need] in meeting life's needs.
