car trouble

OK so last week was very interesting for me...so first on Wednesday i get home and pull my car up in front of my house...and all of a sudden i get a phone call so i turn my car off and start talking then i grab my purse and stuff lock the doors close it and the keys are still sitting in there...but it could have been worse at least i was at home...so i have to call my dad to come home and unlock it for me...but better yet the next day was the Chicago trip....we are already in Chicago when i get the word that i left the head lights on in my car.....we didn't get back 'till almost 8 that evening...so of course i get there and my car is dead....i had to get a jump and have not had any problems since so hopefully it stays that way...
