Phone bill arrives and its a bit more than normal. I log in and look at the itemised bill and see that someone has been calling mobiles from the landline. Looking at the date I had a sneaky suspision that it would be DSS as he was staying with us that week and my kids don't tend to use the landline but I didn't say anything.
DP comes home and I say "look at this phonebill, it's a bit high because someone has been calling mobiles. He looks at the list and there are a small number of calls to one mobile number, one of them lasting almost half an hour. He immediately starts saying "that's not on! I'm not happy about this! I know it's not me and it probably isn't you so who has been calling mobiles? half an hour is taking the piss! I'm going to get to the bottom of this!" (he's implying one of my kids are to blame here).
We both put the number into our mobiles. Mine doesn't come up with anything. DP's phone comes up with DSS's girlfriend. So it turns out it was him.
DP goes very quiet and then says "well, to be fair it isn't a huge amount is it? not worth getting worked up over." !!!!!!!!!!!!
He then finishes it off with "little monkey that he is!" oh my god this little monkey is 18!!!!!!!!! Christ on a bleeding moped.
