Don’t like to initate but no one start talking

I realised that in the gym or in college … always I am the one who say hi and start the talk … some people if I didn’t they won’t come to me

So I don’t like to be the one who always say hi and initiate the conversation … but at the same time if I stayed silent no one will come and talk to me

So I don’t wanna talk but also if I stayed silent nothing will happen
