Forgiveness is Not Normally Easy
Forgiveness is one of the hardest things to practise but we all must try. There are some things we find naturally easier to forgive than others. It varies for each person for example if you accidentally ate someone's lunch in the fridge one person might be really angry with you, whilst another person might be totally relaxed about it and find something else to eat.
The things that are important to you are different from the next person so you will find some things easier to forgive than others. Some may be so hard to forgive that it may take years to get there.
You'll hear songs about family members that have forgiven each other and are finally talking to one another once again. Often they remark at how they can't believe it had been so long and wished that they had sorted out their differences much earlier and that it was time lost.
