Bus seat theories
Sir, – I took a bus recently and noticed that all the double seats upstairs were occupied by a single passenger, each existing happily in their own little orbitals.
It brought me right back to Leaving Cert Chemistry, 1974: Hund’s Rule of Maximum Multiplicity, the Bus Seat Rule.
I had never seen it in practice before but knew that information would come in handy some day. With the Leaving Certificate chemistry examination tomorrow, maybe it’s a sign. – Yours, etc,
