Haha - fab!  I found the present perfect a pain to teach at first!  It's nice when it all finally clicks!

I am getting the hang of it now... my best bits at the moment are tenses!!! Yeaaahhh!!!

Aww it will all become clear once you've taught it a few times!  I used to hate teaching grammar, but now I love it - it's nice when you find a way to make it really clear in a way that students get it quickly!  It's very rewarding :-)
