Let your children see you have fun. Sprinkle it in whenever you can; Sing while you're stuck in traffic, dance when you're cleaning the kitchen and laugh at your own mistakes. Fun doesn't have to be reserved for weekends & vacation. Show your children how to enjoy life even in the mundane routines; they'll watch, learn and do the same.
If your psychic power is strong, you can cause people to feel your presence when you are thinking about them.
If they are in your mind a lot, this can become a kind of accidental enchantment, causing the other person to think about you constantly too. This is psychic influence and it's why you should be mindful and careful if you're gifted.
People with discernment will feel it when you are intentionally or accidentally imposing yourself upon their mind.
But sometimes it can also just be a genuine, deep, reciprocal psychic connection with someone. I suppose the fun is figuring out which it is. Call it psychic flirting.
