Is there a happier soul than Novak Djokovic in the world right now? I wouldn't bank on it. The Serbian star seems to be having a right laugh thus far in 2015.
Let's just forget the ongoing Australian Open for a moment. This is a guy who earns millions upon millions of pounds playing the sport that he loves. He travels the world, supported by a legion of loyal followers, and gets to meet the coolest people in the coolest places. So, job-wise, yeah, he's good - oh, did I mention that he's world number one too.
How about personally? Well, the Serbian star has recently married his long-term sweetheart and the couple are getting to grips with parenthood for the first time. Sounds pretty good again.
It's going pretty well so far, but where's the proof? Enter the first Grand Slam of the year - the Australian Open.
Djokovic, despite his steel-like nature on-court, seems like an extremely happy fellow who passes out chocolates to journalists and doesn't mind distributing some of his various winnings to charity.
The reasons to be happy are just pilling-up. In terms of adding an eighth major title to his collection, things are also going well. One of his main rivals, Roger Federer, has been shocked in the early rounds while another, Rafael Nadal, faces question marks over his second-week durability after some damaging injuries.
So, seeing the others struggle and his own game progress impeccably once more (no sets dropped yet), Djokovic even had time to engage the crowd, persuading them to sing a rendition of happy birthday to his own mother.
The announcement, made after his trouble-free win over Fernando Verdasco in round four, drew 'awww' moans from some of the crowd members. Perhaps it is this air of love and joy that prompted one fan to get down on one knee in Djokovic's presence.
During the encounter with Verdasco, the crowd member proposed to his girlfriend on the 'Kiss Cam', and those in attendance were similarly enthused when the lucky lady said yes. Though, to be fair, the bloke has been clever - without sounding like a kill-joy (I could think of stronger word), this woman would have found it difficult to refuse.
It may not seem important, but these stories of calmness and happiness help one think that this will be Djokovic's tournament once again.
Everything is plain-sailing, unlike his ragged opponents, and you really are struggling to see who will stop him. Andy Murray? The Scot is certainly resurgent, but he probably won't be able to maintain it deep in the second week.
Fifth Aussie crown?
No, barring something special/horrible, you have to feel pretty safe in suggesting that the world no.1 will walk away from Melbourne as the champion for the fifth time - roll on the second week...
