Speaking of computers, when I was taking Computer Science in university, I often had to stay late to finish assignments. My parents worried about me, and when they found that I could do my assignments at home if I had a computer and a modem, they immediately bought them for me. It was one of the first IBM PCs (the one with two 5 1/4" floppy drives). The entire package (computer, modem, printer, software) cost $7,000 in 1983 dollars - so, a very large cash outlay. I used the bejeebers out of that thing.
The somewhat-cheapskate part came later. About ten years after I'd graduated from university, I mentioned to my parents that I was getting rid of my IBM PC. Mum asked "Are you going to sell it?" "Er, no. No-one will want it. It's too old and out-of-date." "What? That can't be right. You have to be able to get something for it." "I'm afraid not, Mum." "Well, at least donate it to a school!" "They won't want it either, Mum! It's too old!"
I could sympathize - they had spent a lot of money on that thing, and Mum simply couldn't believe that it was now worthless.
