Is it okay to try to help a girl who was obviously very uncomfortable in her current situation?
How did you know she was uncomfortable?
I can sense it from her body language and she seems tense.
That is a very kind gesture. Sometimes when we're uncomfortable it can be hard to ask for help, so if you recognize that she's tense and you can help ease her tension, I'm sure she would really appreciate that.
I'm going to go talk to her, but if I mess up it's not going to kill me.
You are a good samaritan and I am sure she will appreciate the thoughtful gesture. You never know who could be in distress and if everyone helped each other like you have, then everyone would be safer.
