Background: HB8 went to my school (graduated), have flirted a bit before. Nothing too crazy. Haven't seen her in a month or so..
I sent out a mass text tonight to about 15 girls:
Me: whats up with it vanilla face?! (good return rate on this btw)
Her: Hahaha nothing im so bored! haha you?
Me: hey hey now its a friday that is relatively unacceptable..i gotta tell you a really funny story later

what are you up to tonight
Her: I know im lame haha my friend that was visiting me from washington left so now i have no rides anywhere and everything is boring haha. Soo nothing really.
Her: And tell me now haha i wanna know!
Me: dork you gotta work on that license umm.. start mountain biking for starts! I will tell you story later too lazy to type and im super occupied haha how bored is bored? (i sent more after this but it got cut off)
Her: The 28th! haha then i will finaaly be able to drive haha. Like 2 weeks. Well fine, but u better not forget haha. How bored is what? the text like cut off
Me: Well remind me loser.. you know i don't exactly have the memory of an elephant these days haha. Bored enough to separate the lucky charms from the cereal flakes (this is what got cut off so i resent)?
Her: Mmhmm and why is that? I still say u tell me now cuz im really bored but i suppose i can remind u. Haha yeah i am just that bored. Tho i would rather just eat the lucky charms instead
Me: Hmm Hmm see you're just all about the instant gratification not willin to work to separate the prize from the flakes! its hard work i'm sure but with great power comes great... oh wait wrong movie
Her: haha what does the last part have to do with anything? yeah but see im not tryin to eat just the marshmellows i like the whole thing. the marshmellows and the little other pieces even the whole thing out. Unlike you i am a cereal expert sooo...yeah haha
Me: LOL thats pretty cute your like a little kroger elf.. i think my messages keep getting cut off how lame i guess if you are more expert than me in one area it would be cereal though ha
Her: Whaaat the fuck is a kroger elf? Haha and yeah they do this one cut off at woul...
Me: You're unfamiliar with those elves? Wtf! They market every good cereal or cookie or carb you could think of
Her: Mmm i believe you are thinking of the keebler elves?
Me: HAHA you corrected me! damn girl you're bad aren't you.. all about the snacks i knew it.
Her: Hahaha kruger elfs haha were did u get that from. Psht duuh im a professional fat ass haha
Me: Haha i donno i knew it started with a k it was my strategy to bring our your inner beauty. But no worries we just hit up Mc Donalds.. altho I had to pass

Her: Yeah i was just lying to bring out ur inner beauty

. Haha nah they really do. But fine haha remember to tell me the funny story later.
Questions:
I like to keep things light and funny but, I feel like sometimes girls just put in "haha" as a nervous sort of thing. I didn't think I was that funny. I'm trying to get more knowledge about texting/etiquette so I'm not really sure if the consistent usage of "haha" is normal or not. Any input most appreciated. thanks!
