Here's a secret that most of my kids are completely oblivious to: right now, I am about to have to bring a student to the table where I am sitting (in the library) for making too much noise. It's one particular table. I just gave them the warning. Now, while I wait for them to screw up again, I have to decide: which of them gets on my nerves the LEAST if I have to pull someone from the table? I will be calling over the least irritating student.
If only they knew.
