A lot of people feel lonely inside. Even if they don’t look like it. They might even be surrounded by many people and still feel it.
Make sure that you’re alleviating a person’s loneliness through loving attention when you’re meeting them. It’s compassion. It’s what Love does.
Assume that a person feels lonely until proven otherwise. Seriously. Loneliness is not an exception, it’s usually the norm.
The best way to teach yourself being Love is through being there for yourself first. You will then be Love for others too. (I think the skill transfers less the other way around. Loving yourself is usually less intuitive.)
