Tears get a bad rap for being a symbol of sadness, but any strong emotion can bring them out ー even positive ones! Sometimes you find something or someone so funny that you laugh until your face hurts, your stomach feels tight, and tears are rolling down your face. It's one of the purest forms of joy that should be relished whenever you have the chance to experience it.
Zenitsu Agamatsu (from Demon Slayer: Kimetsu no Yaiba) looks like he's overflowing with joy as those around him help him celebrate his birthday.
Have a look at some of the tearfully happy illustrations below and see if any put a smile on your face.
