Can I pretend today never happened??

Today I was supposed to be home working on my mid-term.
The disk from the text book company wouldn't open. Many e-mails and phone calls to the company got me no where. The download froze my computer. The rep said he would e-mail the attachments they didn't come, he said go to the web site I couldn't get on without the log in that was - you guessed it - on the disk!

Gave up started trying to do it manually. The computer would not stop trying to outthink me. It did not like the idea of questions followed by multiple choices and insisted on renumbering them. Wasted hours on this! Called the rep, she got snotty, I hung up.

Went to get DD1 at school to take her to scouts. We get to scouts there is no one there. Go home double check my e-mails - no messages, call a few people no one answers their cells, call the scout leaders house her son says she is at the meeting! Which would be where exactly?? Drove back to its usual location still no one there. I say forget it we go get DD2.

While I am waiting for DD2 the doc calls about DD1 and her fall earlier - seems she needs xrays. Tomorrow. I have to cancel all of my classes.

I know I am lucky. DD is really OK, I will figure something out about the exam - maybe I'll assign another project instead?? I know the scouts thing is just another miscommunication and I barely care any more. DH has a job. Life is good. But, can I skip today and pretend it never happened?
