S's clever husband

• Something that you write, you must be very careful, include your emails. it is not like speaking
• Even developed the model out, still keep it to himself, report a long time cost for it and do something himself in this time. as his manager don't know how long it going to take.
• Models is out, he let other people to show it. he is writting papers, that is his own business. Model belong to company, his manager just see his busy there typing every day, don't know what he is doing.
