Just have a talk

You decide to just walk up to them and strike up a conversation.

You start walking a little faster then you catch up with them.

"Hi are you going to the sauna too? Can I walk with you? I kind of don't know the way there." You ask them.

"Sure" they tell you.

"So what are your names?" You ask the girls.

"Well my name is Anna and my friends are Jennifer and Benthe." She tells you.

You just walk a bit and the girls start walking towards eachother.
