[Prepost note - I am suffering from severe anxiety at the moment, awaiting treatment and have a tendancy to fixate on things and make a HUGE issue over nothing]
We had 2 sofas 13+ years old, bought a new one. Biggest one was knackered so DH sawed it up and put into the local tip. He offered smaller, better nick one to DH's colleague for free. He said yes. This was on/around 4 March.
Colleague still has not arranged to collect. If someone was offering you something for free, wouldn't you arrange to get it collected ASAP?
