The clumsiness moment

One sunny (in fact it's super hot) day, I felt like calling her....
We talked on the phone for an hour plus, but it come to a climax when she said "HAIZ" , the phone just auto restarted by itself!  I panicked ....

I always happens- afraid that she will get mad or sad or emo, but hehe, that's just my thinking ;P

To the guys readers, did you ever encounter such event's like this? Or you have other experiences to share with us?
To the girls readers, have you ever encounter a guy who gets clumsy, shy or just do something awkward when you approached him?
