Yes, the sentence "Since you didn't take my advice you must make your own bed and lie in it" is logical. It means that because the person did not follow the advice given, they must take responsibility for the consequences of their actions.

This saying means that you must deal with the consequences of your actions or decisions. If you make a mess of things, you are responsible for fixing it. It emphasizes taking ownership of your choices and their outcomes.

i will give u an example. if someone was really mean and then nobody was friends with that person and they got upset then you would say to them "you've made your bed so you must lie on it.

you write it you write it

1. "You reap what you sow."
2. "You've made your bed, now lie in it."
3. "You create your own destiny."
4. "You brought this upon yourself."
