I'm sorry if I misunderstood but it comes across to me that you are saying to OP she foolishly hadn't realised the consequences of living rurally. But she didn't request concert tickets in the city, nor is she moaning about wanting to go. The issue is that she doesn't want to go and doesn't want to upset her rellies by saying it was a silly gift
Agree with @slim What kind of fucked up logic do some people have?!
Dear sister.....
"I got you some tickets for a concert (that you didn't ask for - but I know you will love because you like the band,) that will take a 5 hour round trip to get to and from. It will involve an hour's drive to the train station, a 3 hour round trip back on the train (that changes trains part way,) and then an hour back from the station to your house when you get back to the station.
By the way, you will need to leave before the actual band comes on stage, or you won't make the train connection. OR you can book a hotel that will probably cost a hundred quid as it's the weekend.
Problem? Going to cost you around £250 in train fares, taxis, food, and hotel bills? Tough shit, you chose to move to the sticks you fucking ungrateful twat.
Now take the bastard tickets and quit whingeing, I heard you say you like this band at least twice, so suck it up, and get a backpack, and fill it with cheese sarnies, crisps, blue riband bars, and some pop, and a flask of coffee, and make a weekend of it, (in a city you never wanted to go to, to see a band you never asked to see.)
If you don't I will assume you are a horrible ungrateful cunt and will never buy you fuck-all again."
Your brother.
p.s. You could fucking drive there too. It's only 5 to 6 hours there and back in the car. Loads of people do it all the time, and there are 1000's of free parking spaces when there is a concert in a major city at a major venue, and you will have no problem finding a space. You won't have to pay for the car park either, as they are all free. In fact, I think most cities don't charge to park now.
And think how lovely it will be driving there in the rush hour with 100's of 1000's of other people, and how delightful it will be driving back in the wee small hours, after nearly 10 hours of being out and driving through the rush hour and battling 1000's of people to get back to the car.
Still, you should be grateful you got the tickets, you nasty fucking ungrateful arse." 
(Upshot is, many people on here are talking utter bollocks, and clearly have no clue about what it's like to live rural.)
