Problem Distinguishing 〜つもり and 〜ようとする


> Ａ「お宅のこうちゃん、薬飲まないの？」  
>  Ｂ「そうなの。あの子、（ ）、いやがって口を開けないのよ。」  
>  １ 飲むことにしても ２ 飲むつもりでも  
>  ３ 飲ませたつもりでも ４ 飲ませようとしても

I chose ３ 飲ませたつもりでも. The correct answer is ４ 飲ませようとしても. I think

> Ｂ「そうなの。あの子、（飲ませたつもりでも）、いやがって口を開けないのよ。」

means "I planned to make him drink it, but he hates it, and I can't open his
mouth.", while

> Ｂ「そうなの。あの子、（飲ませようとしても）、いやがって口を開けないのよ。」

means "I try to make him drink it, but he hates it, and I can't open his
mouth." In English, these both sound fine to me, so I don't understand why ３
飲ませたつもりでも is wrong.

I realized maybe the reason is Ａ is using the present tense, 薬飲まないの？, so using
the past tense, 飲ませたつもりでも, is wrong. Is that why?




～～たつもり(だ) means "I think I did~~".

飲ませ **る** つもりだ "I intend / am planning to make him drink"  
飲ませ **た** つもりだ "I think/believe I (have) made him drink"

So 「あの子、飲ませたつもりでも、いやがって口を開けないのよ。」 would mean "Even though I think I (have)
made him take/drink (the medicine), he wouldn't open his mouth", which would
make little sense.




～～たつもり(だ) means "I think I did~~".

飲ませ **る** つもりだ "I intend / am planning to make him drink"  
飲ませ **た** つもりだ "I think/believe I (have) made him drink"

So 「あの子、飲ませたつもりでも、いやがって口を開けないのよ。」 would mean "Even though I think I (have)
made him take/drink (the medicine), he wouldn't open his mouth", which would
make little sense.
