I am a Potterhead till the very end of it. As someone who loves to collect books, I really want to own the entire Harry Potter book set.

I dunno where JK Rowling got the idea of the Patronus from, but sometimes, it gets me thinking!

If Dementors existed, if the patronus charm was real, if I needed to use it someday; what would be my happy memory?

I honestly think it would change every time I use the charm.

For instances, if I use it now, it'd be a memory of me and my sister. The person who means the whole world to me. Alongside a few other people, of course.

If someone told me to close my eyes and visualize the happiest memory of 2021, I'd say this was the one.

Hip deep in the sea, almost 95% drenched, covered in salt, sea water and sand. 

Just her doing that goofy little march she does and me being her obedient baby, following her actions. After that, both of us bursting into laughter and me hugging her.

I had a fever. I had a sore throat. I had a runny nose. People were watching us. Some might even be laughing at us.

But who the fuck cared at that particular moment?

When all our problems, worries, stress and fear had been washed away by the salty sea? Let the world point and laugh. For all we care.
For me, that particular moment, that particular memory became the happiest memory of that year. And I wasn't going to waste a single second of it caring about opinions that didn't matter.

All that mattered was her and me.
Being the goofballs we are, in the sea. 

Pottermore says that my patronus is a black and white cat. So, now I know which memory I'd chose if I ever had to conjure a patronus.
The one with the sea.
