A while ago I noticed that Nico has this annoying habit of ticking his tongue either before starting a sentence, or after pausing in the middle of a thought. I find it rather annoying, as he does it all the time! For the life of me I couldn't figure out where he picked up this habit.
Well, I was at work one day, talking with a customer and I paused to collect my thoughts. When I continued to speak there it was! The same tick of the tongue that Nico has been driving me insane with for months. In that moment I realized he picked it up from me. I have no clue how long I've been doing this, or how often it slips out. Since then, I've been trying to pay closer attention to my own speech, but it must be very subconscious since I haven't noticed it again.
Being home-schooled, my kids do not spend a whole lot of time with their peers. So, I cannot blame their bad habits on people outside the family. When things crop up, I need to stop and take a good, long, hard look at myself (and their father), to determine where the behavior originated.
