I started crying a bit today and I had no idea why and thought it was so weird that I started laughing too. My friends were like "are you laughing or crying?" and I was not able to respond but thought "I don't know, can't I do both?" x.x it's been a strange day....
I see. Welp crying for no reason sometimes is good for the system. Is just like when you laugh for no reason, you free some stress and stuff either way.
