Our smartphones have become like our wallets or purses- we don't want to lose them and fear they'll be stolen, and if someone asks to look at them or hold them we get nervous, even if they're our close friends.
This nervousness can quickly turn to anger or severe anxiety if the person doesn't give our phone right back, forcing us to think quick and come up with a scheme to get it back without coming off too clingy.
But the kind of person who asks to use your phone is the kind of person too irresponsible to own their own phone and too dense to get why you don't want them using theirs.
So do yourself a favor and avoid letting people use your phone or you might end up giving yourself an aneurysm like the poor guy in this comic by Rebecca Caplan and Kait Thompson.
