Dear Pup,
Well for starters, I am sorry. I know you hate when I leave you and I could tell by the look on your face when you saw my bags at the door that you were not pleased with me. I know this long distance thing is hard for us, but we are going to get through it. And hey, I will be home before you know it to throw your tennis ball outside for you and take you on walks.
I hope that mom and dad are feeding you at the right hours, and are not leaving you starving all day while they are out. I also hope that they are taking you outside and lying on the couch with you as much as possible and reminding you how perfect of a pup you are.
My bed is open for you at any time you may need it. I know it is not the same without me watching TV and laying in it with you, but you did always like taking up the space by my feet. Just pretend I am there with you while you do this, and in just a few weeks, I really will be there. When you lay on the couch, just pretend we are watching our favorite shows on lazy days together. Just imagine me there and I promise I will be there soon.
I guess what I am trying to say is, I miss you. You really are one of the hardest goodbyes whenever I go back to college, and thinking of the distance between us really breaks my heart. I am trying to think of ways to sneak you at school, and I will try everything. But for now, do not forget about me. Do not let someone else become your best pal. And most importantly, do not stop loving me.
Sincerely,
Your favorite sibling
