Hi it’s me again!
First page of this chapter
I hadn’t intended to return to this chapter (at least not for a while) but at this very moment I was reading a Genki lesson and came across たらどうですか / たらどう / たら , which, to put it shortly, Genki describes as giving advice, recommendations, etc. Well, as soon as I read that, the alarm bells starting ringing in my brain that I had seen this before. So I had to investigate, and on the bottom panel on the first page of this chapter, there’s a したらどう! But, not trusting myself with a grammar point I quite literally haven’t even learned yet, just want to double check, is that’s what’s going on here? Seems like it makes sense in this context. The sentence is still a little weird to me with the “become aware of” but I suppose it’s something like a jokingly snippy “You should find out a little about offense already”
