On a recent journey to Finland, I observed that almost all Finns have cell phones and they are, for the most part, made by Nokia of Finland. That means that they all look alike and sound alike, so when one rings in a room, everyone in the room moves to answer his phone.
These cell phones also strongly resemble TV remote controls. In a
gathering place that had a TV, I sat at a table with several people.
When the time came for one particular person to leave, he quickly
grabbed the TV control and walked out. About five minutes later, he
sheepishly came back, replaced the TV controller, picked up his cell
phone and walked out.
