The biggest pimple in the world on your nose is nonexistent when alone. Nude household chores. Toiletries last longer. No one telling you that videogames is a waste of time. Not having to hold back the tears while watching Oprah.
Affairs are guilt-free.
When you croon passionate sad songs there's much feeling. Having a lot more money. Getting to read the newspaper's Sunday comics right away. Not having to lie to a good-looking stranger if they ask if you're single. I'm not saying you should be single forever.
