My favouritest ever band in the whole wide world

are due for releasing a new single on the 26th march called See It Like A Baby. It has the usual inspiring lyrics that makes me love this band so much.
Basically the lyrics are 'remember how good those first experiences were'. The feeling of falling in love for the first time. The first time something excited you as kid. The time you got that new job, the first time you kissed, the first time you got drunk, the first time you had sex. Your wedding day ........
What would be the one experience you'd love another go at, to be able to see it like a baby?
