I was texting my friend and we were talking and my second to last txt said "yah that's" funny" and my friend got this txt and the next morning she said that she got the same text as last nite agian, then later on during the day she said that she got it agian!! On my phone it doesn't show that I sent her the same txt agian but on her phone it does.

Two weeks pass and then she gets the SAME text agian, I don't know why this is happening or of it's common?!?!
