|SONRIE, it might never happen|
I was reminded of this as I cycled home last night as I passed a graffito (yes, the singular of graffiti is indeed a grafito) scrawled on a wall near my house:
Sonrie que la vida son 3 días y ya vamos por el segundo.
Smile, life is 3 days and we are already on the second.
I'm not usually one for smiling for smiling's sake because I think that only devalues the currency of smiling, but I did find this quite profound. It appears to be a fairly common saying in Spanish.
