We never know when a new money-consuming event will happen to us. You can never expect your car to be broken, some payments need to be made, and for this reason when such emergencies happen we often turn out to be unprepared to simply take the needed cash out of the wallet and pay. Borrowing from friends and relatives is not really a good idea, as this might spoil their attitude to you, and you will have to answer a lot of questions. More than that, if you need somewhat like a $1000 or even more, they are very likely not to have it.
