I have a HW and have to make a new plan of conversation or speaking activity for 20minitutes.

I want to know 'what's your interesting speaking or conversation activity?

Please give me some tips!!!
What's a HW?

You could tell about yourself like, where you born, where you lived , how long have you been anywhere, what you have learned from life, and more things like that about yourself. It would be like an introduction but you can do it.
