I made a promise to spend more time at my parent's house but I've decided I'm not going to follow through.
Is not following through a result of you being lazy?
No, I am just very busy nowadays.
It is ok to break a promise if you can't keep it. You should tell them and be honest so they are not as hurt when you don't show up.
My mom will be hurt with it but whatever.
In the future you should avoid making promises if you think you won't be able to keep them, although there are some instances were is truly can't be avoided. Try to tell your parents, specifically your mom, in a kind way as hurting their feelings is wrong and you should show them respect.
