What did this mean ? In theory we should have had an extra $ 1.58 per week , as long as we did n't need to buy anything unexpected such as supplies required ( but not reimbursed ) by work or frivolous things like , you know , shoes , underwear or eyeglasses . We did n't really buy ANY other clothing , relying instead on what we happened to get as gifts . We also did not go to any sort of entertainment that was n't free or paid for by relatives or work .

Question: What may be the reason for trying to budget so tightly ?
To afford to live .
