Tales of the Riverbank - 1960's BBC TV show we watched on Sundays before Davey & Goliath. There was Hammy the hamster Roderick the river rat and GP the Guinea Pig. They rode in their boats and built things and i LOVED them.
ichi-go ichi-e [from Zen Buddhism | Japanese 4-character idiom 一期一会] ~ lit. "one time, one meeting"; often translated as "for this time only", "never again", or "one chance in a lifetime", but a better translation may be “Treasure every encounter, for it will never recur.”
