Lmao!... I know that feeling @meesterboom, not only at work while at school, new friends or course mates are sometimes annoying, a lot of time i have ɓeen trying to avoid them bƴ any means, ɓut like you , no such luck. I get to tell them things to keep them away but no they will not keep away... Interestingly annoying experience.
Ultimately the only thing that s left is the iron hand for them! :OD
