When I was a young kid, I thought we were poor. We always had food on the table, decent clothes (my mom made a lot of them and we did wear hand-me downs if they were still good and they fit) but my dad worked full time and was in college until I was 5. (We went to his graduation from Wichita State.) So we didn't have a lot of disposable income. One time when we were driving to visit my grandparents we stopped for a break and the waitress asked if we wanted anything and I said in a rather loud tone, "No, we're too poor." My parents wanted to leave me there. It wasn't until years later that they realized that overtime I asked for something, the response was, "No, we can't afford it."
Luxuries - I have more than my share. I have been very blessed.
