Look at these two strawberries, one is ripe, happy & juicy looking, the other is going off, mouldy and horrible. When the 2 come too close, the bad strawberry turns the good one bad. This is what happens when you let negative people too close - they ruin your juicy, happy vibe.
Moral of the story is - surround yourself with happy juicy strawberries for that happy, juicy life & positive vibes. It’s not about the quantity of people in your life, but more about the quality.
