DH and I are careful with money, we don't spend on lots of stuff and think carefully before spending. We try to get the best value we can and do buy second hand if we can. I earn a good amount and we have thousands in the bank. However we both came from poor familes and I don't want my dc to worry about food or be cold. So I need a safety net in the bank just in case. The only sent we have is the mortgage and I'm over paying on that as much as I can. However at what point does being careful go to far and how do you know if you are tight? I would hate people to think we are mean.
