u/Key-Maximum-6698

Parked outside my house on the main road on double yellows to take a big parcel inside. A bus honked at me as another bus was coming from the other side so both could not make their way through so bus driver honked at me and made rude gestures. Am I wrong in assuming that I'm not in the wrong due to loading during the time where loading is allowed(?) Typically I would not be causing an obstruction but it's due to the fact it was two massive vehicles coming through and it's tight even if there are no vehicles parked up.
