Our little fellow is methodical. For example, if you find that he has done something good, like putting away his toys (read: moving his cars from high foot traffic area to under the sofa), we sometimes give him a high-five. Then, his sister taught him low-five. So, his ritual became high-five, low-five. A few days later, the ritual included a high-five, low-five and a fist bump. Even if you only wanted to give a high-five, you had to do that high-five, low-five, fist bump routine or not at all.
Well, recently, that schedule has increased some more to include a high-five, low-five, fist bump and ting-ting-ting (that is a spot on either cheek with the middle-ting being for the nose).
Even the ting-ting-ting seemed okay till I heard that the fist bump is fast replacing the handshake as it is cleaner.

The fist bump has evolved Darwinian style – going from being perceived as an aggressive gesture to a acceptable, even sweet one

What if the ting-ting-ting becomes a thing too? I am not sure I am up to having random people ting me on my nose. It is precious to me.
Oh well.

Are you sure.. you don’t bump the person who is getting introduced with your nose? (how can i resist the nose comment :))
Oh dear….no, you don’t bump their nose with yours, you pluck it with your hands!
