TIFU, I accidentally spilled my aunt's dead pet's urn

So... My hands are still literally shaking, LOL.

A few hours ago, I volunteered to sweep the living room of my grandma's house. I want to note that my grandma's house is a few walks away from the beach. There's gonna be a birthday party tomorrow for my aunt, who also lives there. I broomed the floor first before I used a wet floor mop. I didn't mind mopping as I didn't have anything else to do earlier.

Then, my two younger cousins, both under the age of 10 were running around the living room, disrupting what I was doing. I had to stop in between to scold them. Their older sister, a 15-year-old, was supposed to watch them but she was too busy on her phone. After a few minutes of constantly scolding them, the kids eventually stopped and rushed outside to the beach, with their sister following after them.

So there I thought I had fewer problems to think about. Turned out, I didn't notice I made a puddle in the corner of the living room that I have not mopped yet. I then accidentally stepped on it and to no surprise, I slipped. Well, I kept my balance as I was able to lean on the wall to my side, but my left arm went rogue and accidentally pushed a metal vase.

I thought it was a metal vase.

It took me a second to realize the vase I pushed was heavy and it had something inside. My heart skipped a beat. I immediately checked the vase on the floor. Note, the vase didn't break, but the lid was open. At first, I thought it was my grandfather's cremation urn, but upon reading the embossed label on the vase, it turned out to be Blackie's. Blackie was a black Labrador who passed away when I was in college. Blackie was my aunt's dog, her beloved 'son' as she is not married and has no kids.

When I checked the vase, almost half of the ashes came out and scattered on the floor. Thinking quickly, I immediately wiped the vase and tried to scrape the remaining ashes to the vase. I then gently placed it back on the side table in the corner. After that, I grabbed my mop and wiped the floor clean. It took me longer to clean the rest of the mess as the floor in the living room was tiled with white marble.

I discreetly cleaned my mop in the backyard and made sure I left no traces of the ashes. Then, I grabbed an empty can and went to the beach.

Yes, you guessed it. I scooped some sand from the beach and added it to the vase. I figured my aunt would notice the change in the weight of the vase as I know she wipes it from time to time. Then, I gave it a mix, to make sure the original ash was on top. After the whole ordeal, I cleaned myself up. The paranoia in me made me clean the mop one more time an hour after the accident. I also checked the floor and it is spotless now. I am sure no one saw me as my aunt was busy setting up the beachfront, while my uncles were fixing the lights outside.

Right now I am typing this, my aunt has not noticed yet, and I don't want her to know this because it's her birthday tomorrow. I will definitely give you guys an update, if ever. Please pray for me.

TL, DR: Accidentally spilled my aunt's pet urn, and quickly added sea sand to compensate for the weight... the day before her birthday.
