Yes of course, Trog. We generally say namaste 🙏

This may not be as informative as what you've written in your post, but it may be a little humourous.

In the last few years, young Americans and some young Canadians are using the greeting, "Yo, what's up dog?"

In an informal setting, and between friends, this is a light-hearted greeting.

But when an older person, such as myself, uses this greeting with his friends, it can be both unexpected and humourous.

Of course, this greeting is totally inappropriate in formal settings or with those who are not friends.

In America I usually greet most friends or acquaintances with a hug. In more formal settings we do handshakes or sometimes if I am meeting someone for the first time I shake their hand. Sometimes (in a casual hangout setting) I like to start a conversation with someone by teasing them about their handshake 😂 Like if their handshake is too limp or maybe too strong, I think it's like an ice breaker? I think in countries where they speak a romance language kisses on the cheek are common. For example this is how I greet my family in Mexico or when I studied in France people greeted like this. I saw someone below commented "what's up dog" 😂 I haven't heard this one in a while, that's funny. Usually I just say "hey, what's up?" or if i'm excited to see a friend after a long time i'll say "heyooooooo!" haha

The popular greeting in India! It's more like Shikamo and Habari; mostly from younger to elder, right?:)

That was quite informative to me, Richard. I hardly heard anyone using Dog in that way!:D Well, I am sure it's just between some close friends who would not mind or else as you said, it's quite sensitive and rude to refer someone as Dog.

Thank you Richard for your valuable and as always, informative comment!:)
