You mean to say that this PCS is the result of your FIRST concussion and you are afraid of a second in the mean time, correct?
Suffering a concussion, then subsequently suffering a second before your symptoms clear up puts you at risk for something called "second impact syndrome". SIS very well may cause life-long deficits or even death.
However, you need only distance yourself from dangerous activity until your PCS subsides. As for this man you speak of, all I can say is be careful. No one would accuse you of being irrational for avoiding him, given your circumstances.
