text messaging - so efficient!

Texting is a fun way to carry on a conversation when one or both parties are out and about.
When the messenging works correctly, anyway. This is what happened last night:

1:04 am: text from me to friend

1:45 am: friend and I have 1+ hour long conversation on phone.

5:06 am: reply text from friend

So here's the three scenarios:

a) friend got message 1ish and replied 1ish but Ididn't get the reply til 5ish. VERY LIKELY.

b) friend got message 1ish but was weird and didn't reply til 5ish because friend is weird. NOTSOLIKELY.

c) friend got message 5ish, thought "wtf is wrong with her?" and then replied.
*Based upon the very boring and non-pissy reply, I'm saying this one is NOTLIKELY.

It's a good thing thing I wasn't some little emo girl. That would play out this way:

"If you don't text me back in the next 5 minutes, I know you hate me and I'm going to go slit my wrists."

oops.
