Imagine going to see your child's pediatrician and, while he's giving you the diagnosis, asking him to "hold on a sec" while you answer a text.
Or, how about this. You have an appointment with a lawyer and bring the gang along, allowing them to roam unsupervised around his office, playing with things off his shelves, opening desk drawers, pushing buttons on his computer.
Or, you have a meeting scheduled with a realtor, but show up 20 minutes late and get fussy when you find out he moved on to the next appointment. So fussy, in fact, that you stand outside his office interrupting his current meeting, demanding to be "squeezed in."
Preposterous, right? Yet, these three random samples are just the tip of the iceberg of what teachers deal with when we have conferences with our parents.
