New_'dandy'_pants?

A few days ago I left a question about 'letting one's hair down'.Did you work out the meaning?In a general sense it means 'to go and enjoy oneself'.On a personal note I've had some good news from home.My sister has been 'through the mill'over the last few months but finally seems to be moving in the right direction and making a 'fresh start'.I'm sure she'll succeed!
