em.. i am in the contrast, if drive for my families, that's no problem.
but for friends, i don't prefer to drive if they live too far away.
for taxi, ask your husband don't pay for that next time, if he don't mind, then doesn't matter la, don't be too little gas, may be he dont' think pay for families is a big deal.. if he also treat your families the same, don't blame he la.
