Exclamations in sentences — oh boy! · 7:29am May 27th
Often, it's no issue for expressive punctuation create a soft full-stop (period), like in dialogue:
"Oh, wow! A present."
But, especially when the exclamation comes as part of a clause sequence, it can get irritating.
Obviously, there are [Dark] & [Horror] tags too, but people seeking those will not necessarily expect them from the start, but rather to appear after they are drawn in — and, oh boy! does the creepy factor ramp up.
