The plumber came again today, and I have I new pump in my boiler, and less gunk in places where there shouldn't be gunk, and radiators which get hot. In fact they get hotter than the did before, which is nice.
I haven't had the bill yet, I'm hoping it won't be too horrendous.
And this weekend my parents are coming to visit, so I'm hoping I will be able to get my dad to accompany me while I look at more cars - for moral support as much as anything else.
I do wish it would stop raining, though.
