The above poem image uses a shenel (my genius word within a word invention), paraphrasing the proverb that:
‘A bird in the hand is worth two in the bush.’;
mixing it with the common opening to a word of advice:
‘A word in your ear…’
3 letters completing a word h(ear)t is probably always going to be worth more than the first two letters without another to complete a word h(ea)d;
thinking of Monopoly myself, where you buy houses and then a hotel; the letters in the shenel phrase (e, a and r) are like houses, and the complete word like a hotel.
*The heading wordplays the phrase ‘Home is where the heart is.’
