You know you've played too much Persona/Shin Megami Tensei when...

[Strawberry]

start rating your actual friends and girlfriend based on Social Link ranks.

Haha, who would do that?! That's just silly.

...when you spend 2 hours inventing your own persona complete with attacks and an evolved form.

When you spend 2 hours trying to figure out what persona you "are" and what your shadow is like.

I've done these both quite a bit

Done both of these.

When "Joy" from persona 3 is always playing in the back of your head when you hang out with friends.

And had Battle for Everyone's Souls loop in your head when taking a final. Makes it annoyingly hard to concentrate at times.

Should do this one sometime and see what happens.

When I label my friends with social links and they're like "Huh? I'm the fool?"

When you set the forum skin to Dark Hour once it's 12:00 at night.

[Symm]

You name your daughter Nanako and set out a life ambition to be a detective.

and

You buy a toy gun from a kids shop just so you can shoot yourself in the face too mimic Envokers.

One thing I am going to do though is when I move to JP, I'mma get a dog and call it Koromaru. No joke.

When its foggy out and you put on glasses and expect it to make things clearer.
