Does it require more? Well there's no specification as to whether it's soya, oat, goat, skimmed, semi-skimmed or full-cream organic unhomogenised Jersey (they're in my order of increasing desirability, which indicates increasing potential for lachrymatory output), so yes, it isn't that simple! And don't get me started on spilt beer (unless it's American beer, in which case the crying will be of tears of joy).
