Just enjoy yourselves, and let me know one way or another. Just be careful, of course.
Need and want are two different things. If you see something that is calling your name there is no point in depriving yourself of it. You are allowed to spoil yourself. And only you will know how to do that. And if you do not want me to use my chip to get it, then I can give you some twencen things and antiques that you can take to the people who buy those things to give yourself a higher credit limit.
And before you ask, I do not do this for some sort of repayment later. I know you will watch my daughter's back as she will watch yours, and that is enough.
