now if we look at the coffee cup here, we can see that you are correct, it does curve, but that does not make it immediately tea,
for examples, here are a few that resemble our little cup here
so yes if you look at the tea perspective here, it does look like an coffee cup,
but sadly, your side if uninformed of how coffee cups look, let me show you a few:
coffee cups, can look hemispheric too,
so by concluding it by its shape makes it an tea cup, would be horribly incorrect,
I stand by that this is an coffee cup, and I hope your side will review your case some more, mistakes like this lose cases mate
now its your shot, I recommend you bring some evidence to conclude this is an coffee cup, or you'll be pentilaizied mate
