Resentment-horrible but yet we always do it

Its amazing how people can live their life, each and every day no matter how much they're suffering. people everyday find out new things about theire life but yet they go on. they live life to the fullest and enjoy every moment of it. how do they do that when the rest of us who hardly have any problems in our life, find it difficlut to live in the moment. we take each and every moment for granted saying that tomorrow we'll do this, next week we'll do that. but what if tomorrow never comes? what if next week what we wanted to say or do would have changed the way something ended. school shootings happen... its not something we necessarily think about but it does what happens if next week some one gets mad... to mad to deal with life and they decide that the only way todeal with the situation is to end it themselves. do they actually think about what could happen? do they know what they're doing? RESENTMENT is a word teachers and other people in our schools would like us to think about and what it really means. but what does it really mean?at http://www.dictionary.com/ it means the feeling of displeasure. but is that all it is? or is there more to it? i think there is. everyday we go to school we see someone we know walking the halls alone but yet we dont say hi...why? do we ever think about the fact that maybe that person is having a bad day and noticed you as you were walking looking at them...or how hurt they feel when you walk straight by them and say hi to another one of your friends that both of you know? in the classrooms when we have a group assignment we always pick either the same people or we alternate our friends...but what about the other people? the people who have no friends in the class...who dont have a partner when it comes time to have one? maybe we should talk to them one day. no take that back, not one day how about the next time in the hallway? we never think about other kids who probably have it worst than us.
