Cordiality

 Such cute outfits.  From the girl's outfit, I would say this is circa 1900. 

Chummy

 Mom has quite the derp going in this photo from yesteryear.  Girls having fun at camp.  I know one thing, I never wore dresses to camp.  

Rainbowy

 It's truly the gift that keeps on giving.  A new flower arrangement every day.

Idyllically

 Such an idyllic 1950s image.  White picket fence and everything.
