eating
Today, more people are living (and, hence, eating) alone than at any other time in history.
weddings
It's getting crazy out there. SPECIAL BONUS!! Other random things that can be bothersome when attending other people's weddings (especially as a single lady).
relationships
It doesn’t matter how many people reject you or how many crappy first dates you go on because you don’t need all those people to like you, you only need the right person to like you.
