"HAPPY BIRTHDAY to this beautiful, fun, free spirited green-eyed girl. You are on your last year of being a teenager! WHAT! Ahhhhh. Crazy how time flies. I love your passion and admire how you speak what your heart says. I love how you laugh at the cutest things. I love how you and I can literally finish each other's sentences or thoughts (we totally have telepathy). I love how you and I are so different but so similar in ways. I love how you can be as free as a bird and a flowy flowery little princess. I just love YOU. I care about you so much and 💖 you with all of my heart. I hope you've had an amazing day with your family!! Lauren don't ever forget I am always here for you if you need anything. God bless you always and happy birthday my cute lil 19 year old!! ❤️" - Ally on Lauren
"Little Ally, not so little anymore cause you’re 22..what the heck..why are we growing up this is weird?!!! No but this picture I feel describes our friendship perfectly. I love laughing with you about random little things, I love being able to talk to you about anything cause you’re always so available and willing to listen to me and my little problems. I love the way your smile and laughter fill up the room all day long, that pretty smile constantly on your face and brightening up everyone’s day. Thanks for being such a lovely human being and always taking your time to make people feel loved and reminded of it. You truly have a special spirit. I love you you quirky little cutie❤️❤️ HOPE YOU HAD AN AWESOME BIRTHDAY IN VEGAS SEE YOU LATER HUNNN WOOOOOOO" - Lauren on Ally
