Thext: Strange things

Strange things

Jackie and Harold are spending some time together. Jackie– Have you been working too hard, Harold? You don't seem your usual relaxed self. Harold– I haven't been working too hard, but there have been some strange things going on and I've been closing my eyes to them. Jackie– What do you mean? Harold– You know I've been working at the science laboratory for the last two months to discover that new disease. Last week my manager sent me a new helper. His name is Mark. The first time I saw him I thought he wasn't an honest person. I've been leaving all my instruments in the same place every day to know if someone touched them. You know, the magnifying glass, the microscope, the test tubes, the petri dishes, the flasks, etc. The day before yesterday I noticed someone had touched my safety glasses, and yesterday my measuring cylinder wasn't in the same place I had left it. Jackie– Do you think Mark has been touching your things? Harold– I'm not sure about it. What I know is that someone has been touching them.
