Here's why I think they make everything better...
A crappy day? Meeting up with a friend for coffee talk is a great remedy. Having a playdate? Coffee is a wonderful icebreaker (especially if you have lots of flavored creamers to make a coffee bar).
In short, it's pretty easy to make me happy... buy me a coffee or find me great deal on a pair of beautiful heels! I'm willing to take donations for the "Make Jen Happy" Fund which will enable me to purchase smile inducing, awe-inspiring shoes. My psyche will thank you.
BTW... this post is riddled with sarcasm, I hope you find a bit of humor in it... :)
