Some people don’t attach value or sentimentality to $5 valentine’s day cards and would rather just spend time with their partner and spending time picking out a good card for each other can be fun.

The card brings the same amount of joy, but you don’t have to spend money or throw it away later.

Blasphemy! How can you look at that perfect hairy specimen and not think that is a good shape?
