Yup. All the time. It started for me because I would leave feeling frustrated and dissatisfied that I couldn't say the things I needed to so I wrote a letter, put it in an envelope and brought it with. The actual handing it over part was terrifying though but I knew it would only take maybe 10 seconds of bravery to do it.... anyone can be brave for 10 seconds, right? After that it just became second nature and now I bring something to every appointment.
