I will answer with my only knowledge. I hope the landlord is satisfied.

Connection point: the seemingly connection between lies and vows seems to be just "words", both of which are person-to-person words. But I think there should be a deeper explanation. I think there are two kinds of lies, one is good and the other is malicious. Then the connection between a white lie and an oath should be like this. In order to fulfill the oath, sometimes we have to maintain it with white lies. For example, it is very simple, such as swearing' I will always be by your side', but knowing what I want to do will make me never come back. In order not to let the people who love me worry about the pain, I will tell them that I will come back before I leave (even if I really can't).

Then there should be a connection between malicious lies and vows. In order to realize the oath to someone, it is difficult to deceive others, for example, the amount ... only the landlord can understand it.

Generally speaking, there is a deep connection between lies and vows, which may be a causal relationship, a turning point or a parallel relationship. Different things have different relationships, right?

Difference: As for the difference, I think it should be clear. An oath is the most important thing to say frankly. Lies are told with a false heart, which may be very important words. This is the essential difference.

I'm only in grade three. I've been thinking about this question for a long time, it's too profound, and I'm afraid I can't answer it ... but since I chose to answer it, I'll try my best to answer it. I hope the landlord is satisfied
