title: recreating iOS SMS/Facebook Messenger text bubble tail
body: <p>I'm working on a chat feature in an app and I was trying to go off the style of iOS's SMS and Facebook's Messenger app for the speech bubbles around the text. My question is how can I make those little tails that come off the bottom left/right (depending on if sending or receiving) of the bubble? I'm having a hard time finding info/tutorial for this</p>
