you always wear slippers in the house because you believe the cold will enter through your feet and make you sick. 

You don´t sit on hard surfaces only on rugs or carpeting because you believe your bottom will get cold causing you to get sick.

You don´t eat yogurt straight from the fridge because you believe it will also make you sick.

- If you own a Restaurant or store and a Customer who used to come regularly finally shows up after a long absence, you show disappointment and ask them where have they been.

- You have a favourite Turkish Soap Opera which you watch loyally. Men - you never refer to it as a Soap Opera, rather a Program or a Show.
