The girl asked if I was a vase?

Girls usually say these things just to make you comfort her, praise her, give her a sense of security, and make her feel that you are her strong backing. Most girls will say this, which means that she is spoiled to you, even if she doesn't like you, she has a good impression on you, but you should not make a promise to a girl easily, if you don't like her or don't like her enough. If you like her very much, you can answer her, "The vase doesn't matter. I'll feed you and fill you with water. " But if you don't like her very much, then you shouldn't say such things easily.
