Weigh - up the importance of the 'summons'. If it is consistently interrupting or attention - seeking, I either make a rule to be left alone for a number of hours unless there is a real 'emergency', or I get them involved in helping me with the project. Usually, it is just because they want to talk to you and we can do that whilst I work. Of course, I don't have a husband, but am talking of others who do this sort of thing at times.They generally get to enjoy sorting or cutting out etc and have a better appreciation of the process.
