"One Level Up" Neighbour

This is so cute..
Me and my housemate was just went back from having lunch when we found this little note inside our apartment..
We have noticed before that every now and then our new neighbour(s) are these guys who seems to enjoy their small little party in their balcony a lot.. When i say neighbour here, i mean "one level up neighbour" who live in the apartment right above ours.. As far as i know, their apartment should have the exact same blue print with mine's.. But i think there are more than just 3 guys living there.. I once met with one of them who just finished swimming and he seems to just get a bad bad sunburn, and then another one who seems to do jogging a lot, and another one who seems to look sleepy all the time, and another one who looks like an adventurous kind of person to me..

Anyway, look at what they sent us..
a lil friendly note from our neighbour..
...ah how cute...
