Is this a coincidence?

work night shift, and every two weeks, I get a call with someone blocking their number out and not say anything..and its happened before, the first time it happened was three months ago, my co-worker George,answered the phone, the number was blocked and the person asked him who was he working with,my co worker George told the caller I amworking with Laurie( me),and so the caller asked him more questions, asking for my whereabouts, I asked George who did it sound like he said he sounds like this manager that work for the company name Jeremy.. then later on my co worker gets a call from Jeremy the manager asking him"so how are you guys doing over there" meaning me and my co worker George,so then a month p by, and the same person calls asking for me, and asking what time I get off, where was I located, so my co worker George tries to get a name this time,but the person hangs up,and again the number is blocked, George tells me it sounds like Jeremy, plus he had just got off the phone with him,and he asked George,"So how are you guys doing over there"...so then I get told from other co workersthat someone kept calling not saying anything from a blocked number, so its been a month,and today I get a call with a blocked number with someone not saying anything, the person just held the phone..later on that night I get a call from my co worker George,saying that the Jeremy the manager wanted to know if he was available for work..I hope my story is confusing, but is this a coincidence or me just looking to much into it?
