elegentry | freaky noises

there are noises coming from next door. Normal noises I suppose, vacuuming, odd clattering sounds, doors shutting and such but- THIS is WIERD. My experience of living here is that no noise comes from that side neighbour. 2yrs or so of a very quiet elderly couple living there, then a year or so of them not living there- empty house. Now someone has bought the house and moved in. They have every right of course but it is so odd to hear noises from that direction. I keep thinking BURGLAR! Haven't met him/her/them yet. They must have reasonably good taste though because they a) decided to live next to me b) drive a red corolla- grin
