The idea is to finish the sentence based on the subject provided by the person that posted above.
You are to give words of wisdom based on the subject. It can be something funny or serious or sexy.
For example - the word weight, the sentence you might give could be - You know you have gained too much weight when even your undies are too tight.
or - You know you need to gain weight when your partner complains you have a boney butt.
"You know you.........when" is to be part of the sentence...
okay - first word "hippy"
