Girls, Why would a girl just come over to help me with tying a knot in a rope?

[Anonymous]

I noticed tonight this girl and I started talking a little at this training session. I was struggling with this knot in rope we were learning. She then came over to help me specifically. Lately she has never spoken to me. Then she started standing next to me and started making conversation with me. After that we were chatting a bit then we had a quiet moment and she said " sorry I'm just a bit tired tonight had an early start". Why would she apologise to me she doesn't even know me.

because they teach women to help others and be kind
so be careful to not mistake her friendliness with her attraction to you
if you are interested in her there should be more than this to make sure

But why say sorry she is just tired when we're talking. Plus she has never helped me in previous weeks. Now suddenly she is willing to help me

We say these things a lot to each other. Like devilish said, we are taught to be "nice" to others and saying "sorry" is part of politeness.
