“then one day, I found a mug of hot cocoa, and I put a peppermint stick in it”
 
“pepper noooooo, that’s a hot drink, not baked gooooooods!”

“You’re a baker, you’re not allowed to have non-baking interests.”
 
Apparently this includes parenting, which explains why her parents are morons.

poor pony so sad

Gah, I wanna punch her parents!  
Especially since they really don’t have much reason to think they know what specifically the mark refers to; It’s rare to just be ‘good at baking’ both in terms of cutie-mark talents and in terms of real-life talents, it’s usually something tied to personal quirks or interests - A talent in making strawberry cakes, a talent in making the food visually appealing, and so on.  
And then a general talent for the ‘art’ stems from a mix of a lot of practice (if you love making strawberry cakes, you get a lot of motivation to practice baking, and then might be able to use that practice on other cakes) and some lesser interest for related tasks (again, if you love making strawberry cakes, you probably both like the taste of strawberries/cakes and like the process of making cakes. Non-strawberry cakes or non-cake strawberry recipes are probably rather interesting)
 
So, these parents see a ‘Hot cocoa with a peppermint stick’ cutie mark and go ‘Clearly, she’s meant to be a baker doing bakery things!’  
As opposed to, say, being interested in winter-sports, selling hot cocoa to her fellow audience members and/or participants - or just an everything-enthusiast that sells hot cocoa everywhere.  
Or a cafe-owner, who’s known for the self-hoof-made decorations and furniture that make up a rather homely atmosphere.  
Heck, combine them; She makes her own cart, her own outfit, and her own recipes, and goes wherever there’s an audience to sell her cocoa.
 
So, yeah, the parents aren’t just being jerks in the usual ‘we know what’s good for you’ sense, they’re also being utterly moronic and might ruin her life by not letting her learn the vital skills that would let her do whatever her talent is.

This particular comic speaks to me. I have always felt like I was meant to do something different. That was not meant to go into business the same way my dad did, or his dad before him, or his dad before him. Being a business man just never felt right to me. At least, not in the way my dad does it. I enjoy writing and working on projects that involve Programming. But my family is not into the whole technology thing. At least nothing beyond having a cellphone and email. Imagine, spending your whole childhood, teen years, and even young adult years, trying to impress your parents but failing to do so almost every time. Being told that you are meant to be one way and that the path you chose, while hard, may not be the best one. But its the one YOU CHOSE. You want to try something different. Find your own way. Because I was never given room to grow or try the things I really wanted to try, I had not clue what I wanted to do in life once I left home. Its only just dawning on me and I feel like I lost so much time getting there. I want to become a great writer as well as an awesome videogame programmer some day. Maybe once I have achieved one of these things, I can finally make my parents proud of me. But until then, I have to keep working my two jobs to pay for living while working on both these things on the side. But I will get there one day. I just wish I had the chance to figure this all out earlier.
