Grammar for dad

'looking back on things, If I had paid attention in my English linguistics class in first year, I definately would have been better with my English grammar (pluperfect subjunctive). That I have not done so, is clearly reflected in my lack of knowledge of various grammatical tenses (present perfect subjunctive). So had I but known that the pluperfect subjunctive and other obscure grammatical tenses interested you so, I would have enquired further to my professors and perhaps have been able to clarify things further for you (pluperfect subjunctive). However, I wouldn't be writing this if I hadn't seen your comment about it on dave's post...(pluperfect subjunctive). However, if I were to continue writing this thing, then I might not do so well on my math midterm...(future subjunctive). You might be interested in this ;)
