Cars!

Is it really worth me having a car?  I have wondered this a few times recently.  My car spends more time parked outside the house than it does going anywhere.  To give you another illustration of how infrequently I use my car I'll say that yesterday is only the third time id have put fuel into it, the previous being mid to late April and the very first time was the day in January when I brought her, Aurora Rover, home.
Yesterday, Edwin and I went to Carlisle to take some of his stuff up as he is going back on Sunday in readiness for his second year of his Illustration Honours course.
As we got near to the lowest of the Carlisle exits, (there are three,) the battery light came on, and didn't go off.  I did go off when we set off back, but soon came back on again, and stayed on for the rest of the journey home.
I rang John where I got the car from and he said it sounded like the alternator and I should bring it in this morning.
So, after a bad night's sleep, tense and tired from the drive, (I was worried that we wouldn't make it back home,) and Edwin had gone to a party, I thought he'd be back around two at the latest, but he wasn't back at gone five, but did come in around 5.30am.  So...I didn't sleep much last night, I took Aurora, she does need a new alternator, so that is an expense I hadn't anticipated. 
I'm really worn out now, and half asleep, due to the rather long walk back from John's, both dogs are flopped on the floor, dozing.  The funny thing is Spark, who was 12 on the 21st of August, seems to be less tired than Shadow, and she's not 8 until the 18th of this month.
If my arthritis wasn't getting worse I would seriously consider selling my car, but I don't think I should in the long run as there will come a time when I will need to use it more than I do now.
