In Bad company 

"It's better to be alone that to be in the bad company."- unknown 

This quote is saying that is ways better to be alone than hanging out with the wrong people. For example, its better being home studying and doing your homework than going out to party and getting drunk with people so its better just to be alone most of the time. Another example is that some of your friends invite you to go do some drugs and lets say that you went with them and you guys got cought with the cops there is always a consenques to bad actions but lets say that you did not go you went stright home and do whats right nothing bad happpend to you so its just better to be alone than with bad company. Because if you are with people that are bad company you will most likely do whats wrong but if you are alone you will do whats right.
