9. Because you can share it
And this is nothing like that failed experiment in philanthropy the double popsicle sticks were (one person always got a little bit more than the other). Because there are so many possible combinations, cut your sammy in two and trade halves with a friend, to see if the grass is really greener on the other side. (But because in this case the grass is warm cookies and ice cream, it’s greener than celebrity lawns during the California drought.)
10. Because the physical act of eating an ice cream sandwich is intensely gratifying
There is an unspoken ritual involved in eating an ice cream sandwich. You can feel the weight of it in your hands and the density of the ice cream between the cookies as you bite down. The exhale of cold from the newly bitten scoop of Chocolate Chip Cookie Dough. The chomp of macadamia. A chunk of chocolate. There’s so much more to eating an ice cream sandwich than just shoving it into your face; this isn’t an ordinary desk-lunch sandwich -- this is an experience.
