Call a cab, call a friend, but please don't drive drunk. It's not to be taken lightly. I now two people affected by the actions of a drunk driver. My friend who is a very special person lost her son to a drunk driver and it's hard to see how it still affects her many years later. And recently I just found out that my friend's aunt was hit in a head on collision by a drunk driver. She's not expected to make it. The drunk driver is waiting charges depending on whether she lives or passes away.
Drinking and driving is irresponsible and your putting people's lives in danger. So just don't do it. This events are life altering and it shatters the lives of everyone involved. Just don't do it
