this is a problem that i do not understand. when the phone rings, i do become 'paralyzed' and i would agree that it is probably a mini-shutdown (that is a good way to put it).
back in the day, professionals called it 'social anxiety.' oookay
there is no routine that we are aware of in regards to incoming calls. it is off-putting for me because it is something that i did not expect. talking to people is draining for me so when people call i almost feel as though a vampire has arrived to suck my blood.
to me, a vibrating phone communicates 'i want something from you, i want something from you, i want something from you, etc.' this is scary to me.
