You must leave as soon as she comes.

Oh golly Tang this time you've really left yourself (or herself) wide open, with no complex pun intended

The alt meaning is positively hilarious and thanks for making my day

Do forgive all them puns. Do Sometimes take credit when accidental

Oh and yea Tan, otherwise they mean pretty much the same thing

No native speaker would use the second sentence. We use no sooner about events that happened in the past.

You may deduce that.

Thank you.

You're welcome, I'm sure, Tan Lay
You're welcome, I'm sure
