n. behaviour that is helpful to others but clearly requires self-sacrifice

Minor inconveniences—what a pain! What if someone could magically cure these everyday, common ailments. For instance: you are wearing cozy, warm socks and all of a sudden you step into a puddle of water and then BAM, your socks are a soggy mess. What if a hero could deliver you a toasty pair of fresh socks? Or what if you forgot your lunch at home and your tummy won’t quit making angry grumbling sounds? A savior could save the day and deliver you a snack and make you and your stomach very happy. Look out for other people’s minor inconveniences and maybe someone might look out for yours!
