Tools are sometimes not nearly as convenient to use as they should be.
I have to deal with some back taxes and have to submit some supporting data. I could just scan it in and send the files. Right?
Unfortunately, setting up an account with Canada Revenue Agency is not that easy. I start off in restricted mode where I can not send files. Sending files is why I wanted to set up the account.
There is more. Apparently, even after getting full access, I have to send the files one at a time. I have about thirty files to send. No, they do not accept .zip files.
So I am having to print out my scans and mail the works. A bother to print out each file, and then, I ran out of printer ink. Being smart, I have a spare. At this point, I found that I had been sold the wrong cartridge, and not being so smart, I had not noticed at the time.
Should we have maybe stopped at fire and the wheel?
A SoraNew24 article has this as its last paragraph: “As for the taste of this meaty monstrosity? It has all the classic taste of Cup Noodle but with more in the way of chunky goodness and meat sweats, although that may just have been us. Finally, there’s a Cup Noodle that contains two of the main food groups, bird and mammal. Cup Noodle and questionable meat lovers rejoice! Unless they sell out, like last time.”
The issue: “sell out” can means sold all of something and have no more or to compromise one’s ethics. Either might fit.
Five friends (Allison, Beth, Bob, Sue, and Tom) live in consecutive houses on the same side of one block of an east-west street. There are only the five houses on that side of the block. From the clues, determine who lives where.
Bob does not live at either end of the block.
Exactly one girl and one boy live next to Sue.
Tom lives west of Beth.
Bob lives east of Allison.
Usually, the friends meet at Sue’s because the total distance everyone has to travel to get there is lower than that for any other of the five friends.

I hurt my arm recently. It is one of those cases where moving it can be jarring or even painful, and so can not moving it. And which did it kept changing.
I really did not need a reminder—or several or many, actually—that pain is a real attention-grabber. Waking out of a sound sleep early in the morning to pain is not my idea of “Rise and shine!”
May you not get any such reminders.
I hurt my arm recently. I have thought at various times: “My arm is better.”
The issue: “better” could mean that my arm is back to normal, or it could mean only that it has improved but is still not totally healed. Unfortunately, the latter is the case.
Having survived the zombie apocalypse of last week, you are sending auntie Lucinda a card to let her know you are sort of OK. You have a limited supply of hugs and kisses: two O’s and three X’s. You will send her at least two. If the order does not matter—XXO and OXX would be considered the same—how many possible combinations do you have to choose from?
