I think it would be more devastating to humanity if everyone developed and allergic reaction to vegetables.  If everyone was allergic to friendship they would be lonely. If we didn't have friends we wouldn't become better people, and we wouldn't have anyone to relate to. I am very happy that we are not allergic to friendship.  I can't imagine what it would be like not to have friends helping you out, encouraging you, and sticking up for you. I am very thankful for all the friends I have.  Thank You Yahweh for friendship
