Writing: Subordination and coordination — Harder example

my grandfather often tries to persuade me that he is still groovy but how groovy can he be if he still uses the word groovy how'd you like the way that that's written because they're saying my grandfather often tries to persuade me that he is still groovy and that means kind of cool for those of you who might be too young to know what groovy means but that's that's a good point but how groovy can he be if he still uses this word groovy so I like that this but kind of you know it's kind of turning the tide on the first part of the sentence so I and that's why you would use a butt butt so I I'm leaning towards no change but let's feel good that we can rule out the other choices my grandfather often tries to persuade me that he is still groovy because how groovy can he be if he if he still uses the word groovy well because implies that the grandfather does this thing because of this thing so because of how groovy can he be that's the reason why he tries to persuade him or his granddaughter or his grandson that he's still groovy no that doesn't that doesn't that doesn't make make sense my grandfather often tries to persuade me that he's still groovy meaning how groovy can he be if he still uses the word groove you know that that also doesn't make sense because meaning would would mean that there's some type of clarifying that is going on of the first part of the clause and that's not what's going on here you actually have kind of a opposition to the first Clause it's kind of contradicting it a little bit it's like how groovy can he be if he still uses the word Groovy's and that's why but is a really good thing there my grandfather often tries to persuade me that he's still groovy since how groovy can he be if he still uses the word groovy so once again you know since kind of draws a natural a natural cause and effect since this this is happening but it isn't it isn't since how groovy he can be how groovy can't he be if he still use the word groovy that's not somehow causing him to to to persuade his grandchild that he still grew so this also doesn't feel right at all I really like this these two clauses are kind of an opposition they're kind of country they don't contradict but this second Clause opposes the first one in kind of a fun way it turns the tide back on it by using the word groovy itself so it's actually just a fun sentence so let me actually fill in the answer don't want to forget filling in your answer
