Do you have any idiosyncrasies??
I grew up in a house where we had a wall clock in our dining room but it was a small condo so you could see it from every room on the main floor. I used this clock all the time. It even used Roman numerals and would "ding" every 15 minutes.
Now that I have my own home we have 3 wall clocks on our main floor. The dinning room, family room and living room. Most people use this clocks as decoration but I seriously used them all day. We also don't have cable so we don't have a cable box to tell us the time.
DH and I are also big watch wearers and most of the watches don't have numbers. I also look for a clock when I go new places and if they don't have one I always look for the perfect spot.
Also, it blows my mind when people can't tell time. SIL has a very hard time with time but she admitted my house has helped her get better.
What's your little quirk?
