Bah Humbug: nothing for "a friend"

While I was at the drug store yesterday waiting to get my flu shot, I browsed in the greeting card section, looking for one to send to a friend for his upcoming 80th birthday.

We are in the era of greeting card specificity -- but they left out one.    There were 160 different cards (I counted) in the section "For Him."   But every single one was for a kinship relationship:    Father, Grandfather, Son, Grandson, Brother, Uncle, Nephew, Brother-in-Law.

But not a single one appropriate for "A Friend."   And not even a non-specific one that would do.    What's the problem with having a friend and wishing him Happy Birthday?   Especially on his 80th.   

Bah humbug.
