I'm referring to the traditional sense, of the widely popularized ...wild party.

The idea is that this may be your last chance to be single, so let loose.

If this is the idea, I say you aren't ready to get married, in the sense of how marriage was/and is intended to be.

Traditions change & are heaped with compromise ...and a conglomeration of mixed beliefs.  But, sometimes those mixed beliefs tend to make us a bit mixed up.

It's called doubt ...indecision & misdirection.
