Yes, I am still here, just been a few busy days at work and been too tired to get online when I got home is all!
I really do appreciate everyone's concern. We are really just hoping the note was just an idle threat, as it was received about 3 weeks ago now. Indeed, the police were most definitely informed about the note, and they have put it in our file at the station. They told my husband via mobile phone call that someone was arrested in connection with the note, but they wouldn't tell us any more than that (i.e. who it was or what happened after the arrest).
As far as personal safety, we have been pricing up alarm systems, but don't have the 500+pounds that the companies are asking for, so we're looking elsewhere. I do carry a personal alarm, to and from work. I'm never out alone after dark (never have been while living here, anyway, but especially not now). My work and colleagues are all aware of the situation as well. I do have a colleague that lives in the general area who has a few of same issues as we do, but mostly just vandalism and annoying kids rather than burglars.
We do live in a neighborhood watch area, but we don't have the best of neighbors, to be honest. However, my husband is supposed to be having a word with the lady who lives next to us in our semi. When we did report the first guy and the note, we had the lovely Humberside police helicopter patrolling our area rather diligently for a week or so.
I don't know what it is about our house that attracts people. It does look rather shabby on the outside, honestly, so it may be that people think they can easily get in. Or it could have picked up recently because we have a feeling that the guy we caught runs with some sort of gang or at least a "loyal" crowd.
We most definitely cannot afford to move, unfortunately. We rent from my mother-in-law at a more than reasonable price, and I'm the only one working (at an unstable job) at the minute.
I'm mostly angry at the mindset of people who believe they can come and just take whatever they want for free. I may not have much, but I work damn hard for what I have.
