The one thing that I can guarantee about human beings is that, given time, they will hurt one another. The hurt might be unintentional or intentional but the hurt is painful, just the same.
Now, before you all start thinking about how somebody or other has hurt you, think about how you may have hurt them. If you think about this first, BEFORE, you judge that person, it makes it a whole lot easier to forgive.
And you do need to forgive... because if you don't, you'll carry that hurt for the rest of your life. Believe me, that wouldn't be fun at all.
Once you forgive, you have room in your heart for love. My advice is not to hold onto your grievances but to let them go and make room for storing up more love.... or Tea-Towels, whatever you prefer.
