Life’s is like a box of shits and giggles:

Hello! We have a saying in my community that is sometimes used in responses to someone that is complaining a bit too much about life’s hardships, fouls or curve balls and this saying is, “Well life is - shits and giggles”. The giggles part of the saying doesn’t just mean laughs – it means if you make it through a shitty day your laughing because the next day might be better. Cheers!
