You probably remember your Mom and Dad telling you repeatedly never to talk to strangers, but I sometimes find it helpful. Grocery stores are good places to subtly strike up a conversation with someone who is in a similar situation (too "in love" with food!).
Finding common ground, like the weather, or the landlord, or how to prepare some vegetable you've never cooked before can break the ice. It doesn’t need to get all heavy, you don’t need to be anything other than casually friendly. Just make the slightest human connection with someone else where you work or shop or in your day-to-day travels. Supermarket check-out people love it when people say hello to them, and ask them about their day.
Swap a quick one-liner with another person at the ticket booth, or a postman, or policewoman, or at the car wash. It's a good habit to learn the names of people you see on a regular basis, or who serve you. It's lovely to be a part of a community, and we all certainly are -- even if you live on a mountaintop in the middle of nowhere, you eventually come to a village! Know your neighbors and they'll know you, too. It's a great feeling to know you’re not alone in this world.
