Promises. How is it hard to keep your word? Promises can be simple. For instance, classmate promises to show you his photos (his hobby is taking pictures) but he forget or is lazy enough to do it. Of course there is no trouble. Such situations don't lead to any serious consequences but it is still irresponsible. Such promises easily can be broken because they seem to be unimportant. Honestly, I give such promises, then forget or something else. And I hate that. I try my best to do what I say but for me it is rather hard. Maybe I have lack of discipline or responsibility. As for vital promises, they must be keep.
