We're going to the mountains this weekend - about a 3 hour drive. DH, DS and I are going regardless. We invited SIL and BIL to go along. DH suggested they help with gas since the prices have gone up so much. SIL said that she didn't think they should have to help since we're going anyway. Besides the fact that they make quadruple what we do (which I probably shouldn't even mention), what is fair? We're not going to start a war over this. Just wondering. Other than the added weight of 2 additional people and luggage which makes a slight difference in gas usage, nothing else really changes.
Any advice?
