Children learn that C is for Cat or Cucumber or Cauliflower or Corn or Cake or Caterpillar, etc.
But I would like to take this opportunity to say "Come One, Come All" to ABC Wednesday! We have already welcomed a few new participants during the first two weeks of Round 14 and we invite everyone - regulars, occasional, or new - to ask your friends to join in. I've made so many new friends here in the - oh my gosh, have I really been doing this for over 6 years? Time flies when you're having fun, so they say. Even if you can't post one week because you're on holidays or you're sick or you forget, jump in and post whenever you can. The more the merrier! And don't forget to check that your link works after you submit your post. Go on the home page of ABCW and click on your link and it should come up. If it doesn't, try again.
Anyway, "Come one, come all" is a old English idiom. It would be included in a posting for some event, maybe a play somewhere. Three hundred years ago, travel was a real effort and this was a guarantee that even if you were the only one who came to the event, it would go on and your travel effort would not have been in vain. So come on everyone! Come one, come all, ABC Wednesday will go on. And here is your personal golden ticket to the colossal event!
