You’re at home when you suddenly realize that you haven’t seen Wally in a few days. You start to get a bit worried, and you want to check on him, but you don’t want to just show up out of nowhere with no warning. You decide to call him first before doing anything else. You dial his number and wait a little while, but no one answers the phone. That’s weird, Wally always answers the phone within a few seconds.

What do you do now?
