“Don’t let a little thing like…” is a pattern that means “don’t let that major obstacle stop you”.
It is spoken sarcastically and affectionately with friends.
- Don’t let a little thing like poverty stop you from becoming president!
- Don’t let a little thing like an army stop you from crossing the border!
- Don’t let a little thing like the flu stop you from doing your homework tonight!
- Don’t let a little thing like a broken leg stop you from running in the 100-meter dash!
- Well, don’t let that little thing stop you.
(Here, “that little thing” is whatever major excuse you are using to justify your not doing something.)
The city of Dubai in the United Arab Emirates doesn’t let a little thing like miles and miles of hot, dry desert stop them from enjoying things like the ocean and winter. No, sirree (cute slang for no, sir). They have beaches, aquariums, indoor snow skiing, and a nightclub made completely of ice.
Likewise, Japan doesn’t let a little thing like a tsunami or typhoon ruin your day at the beach.
So don’t let a little thing like World War III (or the end of the world) stop you from studying English every night. I don’t want to hear any excuses, okay?
