And of course Karen would point out that there is an entire market of products targeted to women with callus problems, Matt. At least one of them should work better for you than tearing at your skin for Christ's sake! (Don't even deny she'd also start pulling out her lovely cursing vocab for this too. She might apologize for bringing Jesus into it though.) And she'd immediately start researching user reviews, which ones work best, have the least harmful chemicals and so forth. She'd go to department and beauty stores and insist on getting all the samples for him to try.
