Do you want to look chubby next to her? Then I have an idea: order a t-shirt with her photo on it; it will visually make you look bigger, you'll see.
You misunderstood me. I want people to stop paying attention to the fact that I've become skinny so they don't bother me anymore, so they'll get distracted and start talking about how skinny someone else is – a Sphinx is the perfect option.
