かもしれない leaves the door open a crack

Where the picture shows up in かもしれない

1. 1

   the gap you leave

   明日は雨かもしれません。

   ashita wa ame kamo shiremasen

   It might rain tomorrow.

   はず closes the door with evidence; かもしれない keeps it open.

2. 2

   planning around the gap

   電車が遅れるかもしれないので、早めに出ます。

   densha ga okureru kamo shirenai node, hayame ni demasu

   The train might be late, so I'll leave early.

3. 3

   leaving your own door open

   私が間違っているかもしれませんが、もう一度確認していただけますか。

   watashi ga machigatte iru kamo shiremasen ga, mō ichido kakunin shite itadakemasu ka

   I may be wrong, but could you check it once more?

   The safest way to raise a problem without blaming the other person.

4. 4

   opening a door on the past

   さっきの言い方、きつかったかもしれない。

   sakki no iikata, kitsukatta kamo shirenai

   I might have come across too harshly earlier.

5. 5

   a fingernail's width

   今日はちょっと無理かも。

   kyō wa chotto muri kamo

   Today might be a bit much for me.

   Bare かも is casual. With a boss, keep the full かもしれません.
