<human>: Can you condense the text into three sentences or less?

So I'm a 17 year old boy who lives with his parents and sister. Me and my sister decide we wanted pancakes for breakfast usually its her who makes them but today I was like "You know what, I want to make". My sister was cool with it because it means she didn't have to move. I then went to the kitchen and started making them.

After about half an hour I had finally finished making us both lots of pancakes to chow down on. I give her the plate with her pancakes on and I go upstairs to eat mine while i scroll through Reddit. I take a bite out of the pancakes and they taste really weird and rather disgusting so I put them to one side. 

10 minutes later I hear a bit of chaos downstairs so go down to check it out and my sisters led there with a swollen face struggling to breath, my Mum on the phone to the ambulance and everyone in such a panic. My mum looks at me and says "WHAT DID YOU PUT IN THOSE PANCAKES?!? YOU SISTERS IN TROUBLE HERE" I couldn't think of what i had done so I went to the kitchen and had a look at what I used to make them with. 10 minutes later my sister had been taken away in an ambulance and I'm still completely confused about what i had done wrong.

I went back upstairs and my room smelt a bit like garlic, I didn't know why so i started searching for the smell, I soon realised that it was the pancakes that smelt of garlic and that's why they tasted so horrible. Turns out I put garlic oil in the pancakes instead of vegetable oil and my sister is allergic to garlic.
<bot>: I tried making my sister pancakes and put garlic oil in it by accident, turns out she's allergic to garlic and it nearly killed her
