I am new here on InterNations. I am not sure this topic is appropriate to this town talk section. Recently I have received several twinkles. After spending some time in Googling, I found out Twinkle means saying "Hello".
Question is how I do react? "Twinkle back" is to say "Hello, there" or to reject it?
At first, I thought "Twinkle back" is for me to say "Hello" to the sender. and I twinkled back to a couple of peoples to say "Hello". And then, the sender whom I twinkled back disappeared in the list. So, one question arose. 'Why the sender disappeared? Does "twinkle back" mean rejecting it?'
