Should I be upset?

Sarah
While over the weekend staying at my bfs house. We live an hour apart so sometimes I'll stay for the weekend. As we were doing gift wrapping this Weekend, he wrote out the name tags as I wrapped the gifts. As he wrote my name on a gift tag he mispelled my name. Granted I was pmsing and really upset. However still we've known each other about 5 months now. He apologized and admitted he was a bad speller and ( hasn't written my name much) never meant it to be hurtful. Was I overreacting and letting pms get the better of me or should I of been upset? May be silly but it upset me at the time. He spelled it Sarha rather than Sarah. Thoughts?
