With some honourable exceptions, children tend not to be very good at it. The best place to do it is a debating chamber. You tend not to be as good at it if you're drunk. People who do it a lot with lots of different people tend to get quite good at it, but nobody has any respect for them. Success depends to a great extent on your position on the table.
People spend much longer talking about it than actually doing it.
Most people are reluctant to admit that they aren't any good at it. If you do it too much, your degree suffers. Having more points than your partner can cope with is likely to be counter-productive. Although you'll initially feel nervous about doing it for an audience, in time you'll realise you perform all the better with one. The more you perform with the same partner, the more polished your performance will become.
