There. The arrows point in the directions that you should write them, BTW. In text, it's also a way you can usually tell which is which since text isn't quite so vertical/horizontal with their lines. The fatter end is the start point. So if the fat end is on the bottom, it's either a シ　or ン (this is in more textbook text that I'm talking about >3<)

シ ツ and ンソ are these two. In typing like this you can see (at least to me) the differences a little more clearly than sometimes with textbook text...

IDK if that helped any >3<


._. they don't have a name... they are just a part of the character? I just kinda call them eyes cause they look like they're part of a smiley face...
