Do you remember?

To the one who promises, you may not remember. 

But to the one whom the promise is made to, i'm sure you still remember.

Do you remember the broken promises that people have made to you and have yet to fulfil?
Very often, we do.
Even in the slightest thing like,
"I will give you a ride when i get my car", but completely forgot about me after you got one.
"I'll give you (an specific amount) for your wedding and let's meet up after that cause i won't be able to make it."and 2 weeks later when i asked you when are we meeting up? you answered, "for what?"
"I'll get you anything you want for your birthday." but didn't get me anything in the end.

Because i did not deliberately remember them due to being bitter or upset. We are just wired up this way, where we tend to remember broken promises.
