of an opportunity to skip past

time to slip away

not letting a chance go

pass-out time to do something, to miss the opportunity, to lost the opportunity

(Vulgar) a dancer, a dancing-boy

an expression of mild surprise on someone's unexpected arrival after a long time

it is better to weep in season than to laugh out of season

time past is time lost, a lost opportunity never returns

an arrow shot from the bow and a word said never return, a word and a stone let go cannot be called back
