He's probably trying to tell you something that he obviously doesn't want to tell you. or he's making an attempt at prank calling you, and FAILING miserably. Probably the first one. Are you a girl? He may be ASKING YOU OUT..... *dun dun dun....* so if I were you i'd consider what my answer would be so i'm prepared for when he finally remembers how to speak.
Maybe since you're one of his "girl" friends he's a little self conscious when talking to you? Or maybe he likes you and starts acting really shy when he talks to you.
MY friend has really liked this guy for like, 2 years and she has his phone number. She called him and was like "Ummm..." and hung up. He totally likes you! She always wants to call him but she's always afraid.
How do you figure the second part to your statement Do you mean that in jest or do you mean that seriousness. If it's the first answer I suggest changing your post
Zip is Zoria, and yes she is a girl. Anyways, he may have something he wants to tell you, but then everytime he calls, he just hangs on because he's to afraid to tell you. Either that or he is failing horribly at prank calling you.
