Bullying

Oh I got you, small boy! This is the "valid" proof where my naughty nephew bullying my big kid when we were chatting to each other. You see him kicking the back of him! Don't underestimate the kids, they are smart in taking the opportunity to bully the adults. (He only did this once in a while lah...)

... because they are good friends and wearing almost the same style of shirt when going out to eat. The small boy claimed that his shirt is more beautiful because there's a badge on the pocket whereas his uncle one doesn't have!
