Thinking hard about it - I really can't picture asking my family to chip for anything: mainly because we usually stay with family when we visit them and we're never allowed to give them money or pay for a dinner- something we offer everytime we're there. So it would really be nice to have something to offer back as a thank you
Friends are another matter tho - even if they are the family of the heart

I just had one friend offer up my suv for a trip to another city for a group of 6.
1) I have an Escape Hybrid - it don't fit no 6 adults
2) the person offering my SUV weighs - literally- 500+lbs, my poor SUV strains mightly when he's in it around town - 70 miles or so on an interstate? <shudder>
I replied that a) 6 don't fit and b) hubby and I have noticed performance issues with heavy loads and would prefer to avoid that on the highway for long distances.
Friends' response " well X and I will grab a ride with M's SUV then"
ummm, errr, huh?

what part of avoiding heavy loads was unclear? He and his GF weigh close to 800 lbs combined and they each have a car so why am I getting picked on? yes this is one of the friends I'm worried about when we become
DVC owners
adding insult to injury - anytime he's ridden in my SUV he's complained about how uncomfortable it is for a good 10 minutes after he gets out.
He has a good heart, he takes in anyone that needs a place to stay no matter how short an aquaintance, he is a good friend but darnit I feel like he's being pushy.
<sigh> I guess the point of this mini rant is that some of us would like to be generous but know that said generousity won't be appreciated and will likely be taken advantage off so we hesitate to even start cause we know the likely end result.
Did that make any sense?
