R' Reuvein Feinstein was once speaking to a group of talmidim who were all dating for at least a little while. He asked them what they talk about when dating, most of them answered that they talk about the "important" things like hashkafa etc. He asked if any of them discuss if they squeeze the toothpaste tube from the bottom or the middle, and most of them laughed like it's a funny joke. He then told them that these are the important things to discuss because these are the things that can ruin a marriage.
A few years later one of those boys went over to R' Reuvein to tell him that he saved his marriage. He had gotten married and he is the neater one in the house. One day he comes in and things are pretty messy and he was upset about it, then he walked into the bathroom and stuff were left out all over the vanity, then he sees the toothpaste squeezed from the middle. He was about to throw a fit and he remembered "the shmuz" and burst out laughing...
