Sometimes it's just been a long week. Sure, Alfie Lun, age 2, got the chance of a lifetime when he met the queen Thursday, but little man wasn't feeling it, and that's quite OK.

Alongside his mother, Alfie met Queen Elizabeth at the grand opening of a war memorial honoring the military personnel who served in Iraq and Afghanistan. But amid serene music and the quiet dignified presence of the 90-year-old queen, Alfie grew a bit restless.

Waiting to greet the queen and holding the hand of his mother, Michelle, Alfie did a pirouette of sorts as royalty approached down a walkway. Lun picked her son up, but he still wasn't happy, shaking his head and turning away from Elizabeth. Eventually Alfie handed a bouquet of flowers over to the queen — but not before throwing an incredibly cute tantrum. A clip of the incident started to gain traction online Thursday.

Alfie's mother was dressed in her service uniform at the event opening the war memorial. 

"We shall be forever grateful to them for the part they played," the queen said in a message for the event's official program. "It is with pride that we honour the contribution of all those members of the armed forces and civilians who served our country — at home and abroad — while endeavoring to bring peace and stability to Iraq and Afghanistan."

It's not uncommon that a kid Alfie's age would throw a tantrum. The phase when children are 2 years old, of course, is commonly nicknamed the terrible twos. Acting out in such a manner is usually an expression of frustration, perhaps not understanding a situation or how to complete a task, the Mayo Clinic wrote on its website.

"Young children don't plan to frustrate or embarrass their parents," it wrote. "For most toddlers, tantrums are a way to express frustration."

So Alfie likely didn't want to create a scene meeting the queen, but even in the presence of royalty, kids are kids.
