Hi, have you gone hiking before?
Hi, i love hiking. Its such a good workout with friends 
I think I will like it, but i am afraid of real height.
Aw, well you dont have to hike on mountains, you can hike on more country trails. no heights!
My friend want to take me hiking, I hope she doesn't chose a mountain, I don't want to look chicken.
Aw, well ask about just a day hike, they tend to be shorter. Just remind her you are a beginner, she would understand.
Yes, that sound great, I will try that.
Good, hikes can be a lot of fun, just be sure to wear good shoes, bring water and snacks and watch for your local wildlife.
Thanks for your suggestions.
You are welcome. I hope you enjoy it with your friend. I'll warn you though, it can be addicting!
