If you’re thinking of selling it, note how you feel now. You’re not sure. This is a friend of yours and you’ve resisted him and he’s pushing you to sign up, yet you’re not eager to do so and you’re unsure of the drink so you’re asking people if it’s good or not.
When they start telling you that it sells itself, think about this. A good friend you trust has been pushing it on you and you don’t want it. Do you really think if you’re selling it that people you don’t know will be eager to buy it if you aren’t when a friend you trust is selling it?
