Friends of women:

A wife was not at home for a whole night. The very next morning, she tells her husband that she stayed at her girlfriend's apartment overnight.

The husband calls 10 of her best girlfriends and none of them confirm that.


Friends of men:

A husband was not at home for a whole night. The next morning, he tells his wife that he stayed at his friend's apartment overnight.

The wife calls 10 of his best friends and 5 of them confirm that he stayed at their apartments that night and another 5 are claiming that he is still with them.

Yeah , that is that what are friends for .
