The Christmas Story (featuring Marina (the mother), Olga (the 7-year old), the salesman, and myself:

Marina: Olga wants a smartwatch for Christmas.
Me: Those are very expensive.
Marina: You said she could have anything she wants.
Me: I said whatever she wants from the toy store, and they don't sell smartwatches.
Marina: But that is what she wants and I want her to wear one so I can always find her.
Me: I bought her a cell phone last summer. You can track her through that. Besides, you cannot afford a SIM card subscription. I am paying for the cell phone subscription each month but won't pay for another one.
Salesman: She doesn't need a SIM card. The watch can be connected to her cellphone by Blue Tooth.
Me: But the cell phone has to be very close to her for a Blue Tooth connection.
Marina: She always carries the phone,
Salesman: If the watch is within 10 meters from the phone, there will be no problem.
Me: If the watch is so close to the phone, Marina can track her through that, without a watch.
Marina: What if she turns off her cell phone?
Me: Then there will be no Blue Tooth connection.
Salesman: Should we test it?
Marina: We can't. She doesn't have the cell phone with her.
Me: What happened to her always carrying the phone?
Olga: But I really want the watch.
Me: Okay, I will get it.
Olga: Why do you have to get it? Santa Claus will give it to me.
Me: Santa called me last night. He said he does not want to fly to Israel while there are rockets in the air. He is afraid the reindeer will get hurt. He asked me to buy the watch and said he will send me the money through my bank account.
Olga then gave me a big hug.
Me: Marina, do you also want a smart watch?
Marina: Not enough to give you that kind of hug!
