One or Two Relationships ?
It is like asking someone if he prefer to eat one "char siew pau"
or eat the second "char siew pau" also.
There is such a thing as "diminishing return" in most things.
The first relationship is good, then sometimes, the second
relationship can even be better.
However, if you can eat both, do it, but make sure you can digest
both - either one at a time, or both at the same time.
Don't get choked though...
