If you've made it to your mid to late 20s and beyond without getting married or bringing children into the mix, you're a pro.
At least it's my experience that this unaffiliated status makes you a professional in some areas.
First and foremost, I'm a professional house-sitter. I've got no reason to sit at my own house. Who is there, anyway?
I'm a professional dog watcher.
I'm a professional aunt. No legitimate children to spend perfectly good aunt time on. None to share pictures of until you've hidden me on social media.
I'm often a professional Conway Corp liaison. Since I'm not busy with real responsibilities such as a husband or family, I can and will be called upon at any time to be the buffer between my mom and a nice customer service rep.
I'm a professional Christmas decorations getter-downer.
I'm a professional light bulb changer. If I'm indisposed because of a light bulb changing injury, no one is late to eat dinner or get to school.
I'm a professional dog owner. No one owns a dog like I have the time to own a dog.
If I could stretch this out a bit longer, I'm a professional box of cereal eater - a job I should cut my hours back on as I close in on the death of my metabolism.
