Can you remember your first ever net session?

It's quite likely that your first ever net was pretty similar to the net you had last week. The bowling may be faster and your pads a bit bigger, but essentially the humble net hasn't changed: batting for 20 minutes (if you are lucky) on a different surface to match-day; using old balls; having no fielders; bowlers alternating after every delivery; balls continuously fed; batsmen not running-between-the-wickets; and focusing on execution of correct technique over tactical decision making.
