I also "can" and so can my siblings but I actuallly stopped drinking sugar water but my siblings don't so they are "passionate" about coke and "hate" Pepsi for some reason. I don't understand

Pepsi is disgusting to me. To even speak of them as substitutes is outrageous to me. If you like it fine. I like both mayo and mustard but if someone doesn’t like mayo I don’t recommend it as a substitute for mustard.
