I finished filling out forms to adopt a child and realized, after I'd left the office, that I had no idea what age the child would be. Automatically my mind started running through scenarios of the interactions of this hypothetical child and my three-year-old daughter; the variations depending on the age of the adoptee.

My SO was having trouble reprogramming one of the speed-dial buttons on our telephone. In trying to re-insert the same number as before, he kept hitting the speed-dial button as part of the programmed sequence. I saw immediately that this was creating an infinite loop.
