Talk about her interests

You: What do you like doing?
Agatha: I love travelling, last year I went on a hike to the Swiss Alps, it was beautiful.

She sent you a picture.

You: wow, the scenery is beautiful. I actually visited Ireland last summer, Europe's a beautiful place
Agatha: can't disagree with you, this is the place I stayed, check out the view

You: oh trust me, I am enjoying the view *wink wink*
Agatha: oh shut up :D
