There is a huge difference between blowing yr nose etc when you have a cold, and when u have allergies. If u have a cold, u really should give friends option of canceling dinner and stay home. If allergies, tell yr friends u have allergies. Not contagious. Get up from table for any massive nose or throat clearing but sometimes wiping nose or small quiet blowing of nose is ok. My dh is a really loud nose blower, and if that is the case, yes, should get up from tale every time. |
