The teeth of a dog do not lock together.
If the family is together, the soul is in the right place.
Birds of a feather flock together.
Day and night cannot dwell together.
Get Together Like Brothers, But Work Together Like Strangers.
The poor man and the rich man do not play together.
Lovers’ hearts are linked together and always beat as one.
Fire and gunpowder do not sleep together.
Between true friends even water drunk together is sweet enough.
