Skin care, how did I know?

The other day me and my friend went to Boots, just to brows and we ended up looking at the skin care section and I was showing her my favourite products. A girl overheard our discussion and asked me for my help. She had very dry skin, it looked like she had some kind of reaction to something. Not looking good. I told her that for a sensitive skin Avène is the way to go! She said it was bit to expensive for her right now so I ended up helping her with the lot. I asked her what she was using as a face wash. Now you guys wont believe me, but she said she was using intimate wash on her face as it suppose to be very gentle. I was shocked and told her that it's probably what caused the problem in the first place and normally intimate washes are made for intimate places and they are normally more acidic then other places on your body, that's why it's an intimate wash. She was shocked and kind of didn't believe at first as she's been using it for years. At the end she ended up buying a new face wash. Now, before she left she asked me how I knew all this and I stopped to think... I have no idea! It just came out, naturally and it was very nice to help someone out. She was very thankful and I think felt bit calmer.

So now the conclusion is... maybe I'm destined to work with skin care and make up? What if I am? This was bit freaky. What shall I do about this experience? Was it a moment caught in time or a sign? Will we ever know?
