Several other teachers gave me the same explanation for pushing two spaces on their students. But if you think about it, that's a pretty backward approach: The only reason today's teachers learned to use two spaces is because their teachers were in the grip of old-school technology. We would never accept teachers pushing other outmoded ideas on kids because that's what was popular back when they were in school. The same should go for typing. So, kids, if your teachers force you to use two spaces, send them a link to this article. Use this as your subject line: "If you type two spaces after a period, you're doing it wrong."
6. Other people will assume the ring is made of diamond, since they won't be able to tell the difference. I'm not one to pass something off as another, but the reality is that people are so brainwashed about diamonds that everyone who sees your fiancée's ring will assume it is made out of diamond. (Most of the time, it's not worth explaining to them it's not.) In the 6 months my fiancée has had her ring, 100% of the people who have seen it think it's diamond. If you're worried about a "loss in prestige" if someone notices, rest assured that other people will never know unless you tell them. (Note: do not try to buy your fiancée a moissanite ring and pass it off as a diamond . Honesty is key - talk to her about it first.)
