I really want to be the best at everything, you know what 
I mean? Tweeting is super fun you guys!!!"

tweet2 = "OMG you guys, you won't believe how sweet my 
kitten is. My kitten is like super cuddly and too cute to 
be believed right?"

tweet3 = "I'm running out of example tweets 
for you guys, which is weird, because I'm a writer and 
this is just writing and I tweet all day. For real, you 
guys. For real."

tweet4 = "GUISEEEEE this is so fun! I'm tweeting for you

you know what I mean? I just can never tell how long to
