fns90: Those are good ones! Thanks for posting them.

We also need to practise them otherwise they are just nice statements.

I suggest we also post our experiences.

I was in a store in a line today and I noticed a lady in front of me had candles just like the ones I bought and liked before. First I wanted to say that, but then held myself back since I get nervous when talking to strangers. Then I remembered the statements (12 and 14) and said that those are nice candles. And she turned out to be real nice and we had a little chat. I also said - When you lit them up instead of When you light them up and immediately started criticizing myself for this mistake in my head [English is not my first language]. But I said to myself that it was perfectly ok and we as humans supposed to make mistakes. Overall, I left the store feeling a little happier than when I entered it.
