Train Friends

Train friends are people you see everyday on the train, usually sitting in the same wagon at the same place. Those who take train to work know what I mean. After a few days of having the same routine, you get used to going to the same place everyday, seeing the same faces at exact same seats. Train friends are the ones you say hi to. You may know or not know their names, because one time you talked and asked the names but forgot and now you don't want to admit you've forgotten their names...
