Diaper change time

This actually surprised me:

President Donald Trump said he felt “unwelcome” in London after its mayor, Sadiq Khan, permitted a 20-foot-tall angry “Trump Baby” blimp depicting him to be flown during his visit to the UK.

“I guess when they put out blimps to make me feel unwelcome, no reason for me to go to London,” Trump said in an interview with The Sun.

Khan described the blimp as a “peaceful protest.”

Isn’t Trump supposed to be the alpha male who never gets offended? Did a blimp hurt his feelings?
