DMSI First impressions + beginner question

[lano1106]

I have just read the list of signs to look for and this remind me that this afternoon at the gym, 3 women were laughing very loudly beside me. It was loud one notch on top of what you would consider normal for me to notice and think, Wow they really want the whole gym to know that they have fun...

Again, it is not enough to conclude anything but still an interesting coincidence...
