This also can happen Anytime 

- cause people 'are busy', they forget, etc.

So if this happened to you - try to find out Why the other person failed to follow your Request - cause there can be many reasons, & it's not always Their Fault. - Sometimes the circumstances changed, something unexpected happened - & they just had No Way to do what you asked them for at the time they said they would. 

I understand that you're Not Happy 'because they Promised' - but maybe they can do that later? Maybe you just have to wait a bit longer? - Be Patient 

🔷 Whatever the Reason is

- you have the right to Know it, so they should at least tell you 'why it took them so long' or 'why they're not able to follow your Request'. ( You shouldn't be left without explanation - It's Not Ok if they just leave you like that )

- If something that stopped them happened & you already know that They won't do what u asked them for - You have the Right to feel 'disappointed about that' - but do your best to Forgive them! 

- If it happens for the First time - & everything else was ok - it's quite easy to forgive them. 

💠 But even if you know that they were Not Trying Hard Enough, didn't put enough effort or time into your request & they Could - & if they would they would Manage to do that Easily - Forgive them Anyway. - Cause Otherwise This Situation will be Bothering You - & you'll be coming back to it over & over again - & your Peace Of Mind shouldn't be ruined by that. So Forgive for the sake of Your Own Peace! 🙏  

Cause you deserve Peace.

That's it!  ^_^
