Things that make you go "DUH"

Perhaps this will be a new randomly-populated blog category...

*When reading a bedtime book of facts about guinea pigs to Toby, and the last page is about the lifespan of guinea pigs (and thus when they die), don't tackle the topic of cremation when Toby asks "Mama, how did Patrick become a flower?" (Patrick the doggie was put to sleep last spring, apparently Toby had had a conversation with Terry earlier that day about what happens when animals die.)  If you do, it'll be a very long after-lights-out conversation.

Duh.

*It's no secret that I knit tightly.   At my last conference, I had the usual sock-on-needles with me, and ended up at a bar with a couple of other knitters - where I was teased (it was ok, not in a bad way) re. whatever connection there is between my choice of profession and my tight anal knitting process, I said to myself "I can so too knit less tightly" and I proceeded to do so on the present sock.  In the dark.  Upon arrival back in my hotel, I had an inch and a half or so of the calf at a distinctly different gauge.

DUH.

*When blogging from home on a snow day and distracted, and your sweetie asks if she can close out your blog-post-in-progress window, you say yes as you have set the publishing date to be later that night.  But have you saved the post in question?  No.  It's gone when you log on again later.  Duh...

*When blogging-in-your-head before bedtime, if you don't take notes you will undoubtedly forget fascinating components of a blog entry.  Say it with me now....

Duh.

Feel free to contribute your own examples.  I'm sure I have more.
