The Residence Inn Midtown East has the perfect solution for your case of the Mondays.
From Noon to 4pm today, the hotel is hosting a free puppy party in their street level lobby at 148 East 48th. Head over there during your lunch break to cuddle, de-stress and just be surrounded by general cuteness. (It should definitely be more fun than a sad desk salad, at least.)
And if you really fall in love with one of the pups, keep the party going by taking one of the friendly fellas home. North Shore Animal League America will be one-hand to arrange adoptions that you can celebrate the anniversary of once every four years.
