我忘了學校內聯網的密碼，現在想開

Do u remember who's 學號 is your前/後at P.1/F.1?

As far as I know, in my school, the one who is your 前/後 is alike, like:

abcd145 (the one who is your前)

abcd147(the one who is your 後)

So, u may be "abcd146".

But I don't know if your school is like this, and if u don't remember who is your 前/後, I can't help u (sorry...)

Just try it ^ ^

hope I can help u!

(Sorry I am too lazy so I don't write in Chinese...don't be angry because of English.
And my English is poor so the grammar my be wrong. Just change it into Chinese.
It is like "HK English" XD )
