Why walk at graduation?

I blogged several weeks back that my sister I graduate on the same time on the same day at two different colleges. I was so thankful for the advice all of you gave to walk and to invite my boyfriend. He said he would be happy to go and would love to. Turns out the conference he has been telling me about for work is also at the same time and we didn't realize that until tonight. This conference is where the anybody and everybody he is in contact with throughout the year attends. We just happened to be texting back and forth when he asked when it was. I ran to the bathroom and cried. I was really saddened. I thought it was so cool that he was going to go- a guy that I am in a relationship with cares enough to sit 2 hours in the hot sun to watch me... ME! I officially felt alone. My mom, dad, aunt, uncle, cousin 1, cousin 2, and cousin 3 are all going to my sister's. I thought about how I will be alone. My mom told me Linda will step in, and for that I am grateful. Still... I'm sad. My want to walk suddenly faded again when Mike and I realized this. My friends at school were anxious to meet him. He says we will celebrate when he gets back and he wants pics while I'm there, so that he will get- it just won't be the same. But I will walk because I know I'll regret it otherwise... I'll put on a smile and that'll be it.
