the moment you start to remember the difference between シ and ツ without memory tricks.
Next is ン and ソ.-シ and ツ just look like し and つ to me as far as their shape goes and I’m lucky cause I have ン in my surname so I can always remember. But you are right I don’t even think of those tricks anymore I just read them
I had to step away from my keyboard when I saw this. This is so… simple. /*facepalm*
I was using a complicated mnemonic trick. シツ looks like two shitsu dogs looking at each other. If they’re flipped ツシ they are no longer looking at each other. So I always remember it’s the correct order way, and it’s always shitsu.
