I hope you're having a better day than I am

I'm driving along and all of a sudden my car starts making a squealing noise followed by the red battery light coming on the dashboard. Luckily I was three blocks from a service station, so I pulled in and talked to the mechanic. He said it's not safe to drive the car with the red light on and the noise but he wont be able to get to it today. He took my phone number and said he would call when he knows what's wrong. My brother in law picked me up and took me home. So now I'll be without a car for who knows how long and who knows how much this will cost. Aaaaargh! 😫
