翻译两句话，麻烦别工具翻译，那简直错得一塌糊涂

"I found that I have a mistake - and I asked to forget your birthday!"

I find i made a big mistake that I forgot to ask when your birthday it is.

只有我楼上的同学正确阿，发现是现在的动作，犯错是过去的事情阿

每个人说话的时候，除非特别要表明时间，都是用现在时，用过去时并不总是安全。

难道用 found 说：我刚才/曾经发现。。。（明明发现了，但是过会说是符合逻辑的？）

但也不是说话的这一刻“发现”的啊，当然是用found了，found用的频率要远远高于find
以下情况会说find
一，"I find it!!"
二，"you need to find out"

i find out a mistake! i forgot to ask you went is you birday!

I discovered that I have a fault! I forgot that asked your birthday
