Meeting partner's child for the first time, any tips?

[UserABCDE12345]

'Child' is late teens. Partner and I established relationship that we see a future in. Meeting child soon. Child has previously been reluctant to meet but has agreed now. Any tips or suggestions?

The one thing dd 14 commented on, when she met her df's current girlfriend, was that she was the only one she had met who didn't drape herself over him. Previous ones had all been very touchy feely with him and she really did not want to see that.

She also didnt ask endless questions about school, which was apparently a plus.

You need an ice breaking activity like bowling or crazy golf to take the pressure off.

I had to meet a distantly related teen for the first time a while back and by the end of the round of crazy golf, where we'd laughed at each other's ineptitude, she was much more relaxed.

How late is "late"?

I agree with the minimum affection suggestion for a first meeting. An activity is a great suggestion too, a meal gives too much time to make conversations. Crazy golf, cinema, zoo etc all take the pressure off conversation but give you something neutral to chat about at the same time.

Agree with @Itwasaquarterpast11. I'd keep my hands to myself. Can look a little territorial draping yourself over someone's father.
I'd not ask direct questions. Let the conversation flow between parent and child and join in where appropriate. I'd blend a little into the background but smile and keep your body language open.
