HANDSHAKE
A handshake: it’s a typical way to introduce yourself to someone. But if you think about it, it's actually a bit weird. What if your hands are dirty? What if you don't have hands? And why do we only do it when meeting for the first time, at sporting events, or other important events? Handshakes have been around for ages, but the tradition of shaking hands differs depending on time and culture. Where, when, and with whom should we shake hands? The answers to these questions vary depending on the culture or person you ask. Especially if you develop your own secret handshake with a friend.
