Hello,<br/><br/>Is it okay to use exclamation marks in this manner:<br/><br/>"Yes!" he said.<br/><br/>Normally, we can't use it after a period. "Yes." he said is wrong.<br/><br/>But are commas and exclamations marks fine? <br/><br/>"Yes," he said.<br/>"Yes!" he said.<br/><br/>Looking for some ideas.<br/><br/>Thank you.
