If you give a mouse a cookie...
...he's going to ask "What the **** is this?! No HTTPS? No domain? No expiration date? And haven't you heard about GDPR? Who did even let you close to this code? This sucks! And you call yourself a web developer? Can I talk to your manager? Do they know what a ****** developer you are? Aren't you ashamed? You should be ashamed!" And that's why you never give a mouse a ****ing cookie. The end.
