When you've been looking at convenience store kimbap for about 15 years, you end up knowing all sorts of things.

I know pretty much what's trending lately, what the competitors have put out, and what's selling well. Do I follow trends at this age? No, it's work. Even I eat the same old things once I clock out.

I live alone. I have a house, I have a mortgage, and not long ago, I bought an 85-inch TV that doesn't fit the size of my living room. I regretted it a little when I saw the credit card bill. Not that I regretted buying the TV, I just regretted the bill.

I go to the competitor's convenience store in front of my house. Our company's store is an 8-minute walk, and that one is 1 minute away, so what can I do? Loyalty to the company and laziness are two separate issues.

I like meeting people. It's even better if we communicate well. But at this age, unless it's people from work, there aren't many opportunities to meet new people. Not that I'm lonely, though. I eat well, play well, and live well on my own.

If I had to pick one problem, it's that I occasionally forget I'm forty.

Well, others make sure to remind me.
