Hi Jennifer,
You're absolutely right in this case--"close" is a heteronym ("two or more words that are spelled identically but have different sounds and meanings"). If you look up "close" on the Merriam-Webster Dictionary (sorry, I'd like it, but I'm not sure links are allowed on these posts), first, you'll see the verb entry, pronounced similar to 'nose.' However, if you scroll down, you'll find the adjective definition of 'close,' which as you noted, is pronounced more similarly to 'dose.' The MW dictionary even has the phonetic pronunciations you can use to support your point, including phonetic spellings similar to the ones you used in your example.
If you want to take it a step further, just search up "close heteronyms"--you'll find plenty of articles supporting your point. Best of luck!

No problem, Jennifer. If it helps, the adjective definition for 'close' is kind of far down in the dictionary entry as there are about 10 definitions for the verb definition of 'close.' You could always try and frame it as something that anyone could have missed given how long the dictionary entry is.11/19/21

Thank you so much Benjamin! I feel like I'm in a bit of an awkward position since she already "looked it up" and I don't want to offend her, haha. Really appreciate it!11/19/21
