On a recent episode of How I Met Your Mother, Marshall and Ted decided to take a road trip to Chicago, while leaving Lily back at Crumpet Manor. While the guys were gone, Marshall called Lily several times to apologize for taking off without letting her know. Luckily for her (and him!), she was so caught up in her relaxing treatments that she didn't even know he was calling (even though her phone was on vibrate). After watching this, I couldn't help but wonder what everyone else does with their phone while at a spa appointment or doctor's appointment? I always put my phone on silent during these kinds of appointments because my vibrate setting is still pretty loud. What about you? Do you ever leave your ringer on?
