Apparently, it is incumbent upon everyone else to tolerate your adorable screaming baby.
If after you press the flight attendant call button the flight attendant does not immediately appear, start pressing it repeatedly. They respect that.
The autistic child seated next to me on the plane was better company than you might otherwise expect. Upon landing he pointed to a Canadian Airlines plane and asked, “Why would anyone want to go to Canada?” I said I didn’t know.
He told me that he wasn’t supposed to talk to strangers because they might be dangerous. He then asked me if I was dangerous. I told him that depends on who you ask.
He later asked if I would be sitting next to him on his return flight home. I had to help him unbuckle his seatbelt.
If you prefer to sit in the middle of the walkway near the terminal gate with your backpack serving as a backrest, thereby causing people to walk around you as they struggle to get to and from their own gates, I can’t help but hope that your plane takes a nosedive shortly after takeoff. The other passengers will be collateral damage in the service of a higher purpose. Not unlike the brave men who stormed the beaches at Normandy.
