The first one is about mail brides (more like online dating). I guess mail order brides are like flowers - better give it a day to let nature decide if it is to be rotten or its beauty is to remain.
The second one is about generation gaps. The goats are the older ones, the mouse is in his his 30s, and the pig is a teenager. By stating objects older generation uses, you can easily tell generations apart as younger generations typically don't recognize older objects. The comic here deliberately makes the pig to talk on a cell phone, which is a hint that he is in the modern generation, bringing the telephone booth into the scene.(In Hong Kong, almost all telephone booths are equipped with paid wifi, and they're almost )
The third one represents mean women. Feral means wild, and the ballet dancer who is feral tells us that you should never judge a book by its cover (and to especially avoid women that are too beautiful.
)
I think the fourth one refers to helicopter parents who let their children live in a fantasy world created by the parents. Kids need to realize that reality is harsh, and the progress really depends on the parents' attitude.
The fifth one tells a story, a story current children will never tell.
The sixth one tells that bosses that want to make friends with their employees either success or make them look really annoying.
