L: did you get my email?
Z: I certainly did. Do you want to come in and give me some feedback about your weekend?
L: sure.
Z: how did the business trip go?
L: well, to be honest, nothing is more stressful than going on a business trip with our boss.
Z: I understand. The last time I went on a business trip with the boss, I didn't even have enough to eat!
L: I also think the company is pretty cheap with travel expenses. I spent half of the weekend on a train! Surely they could have afforded to buy a few plane tickets!
Z: our company is quite conscious of the environmental problems that frequent flying causes.
L: I see. Well, then perhaps they could give me a few days off after a business trip. It was really tiring for me.
Z: I can ask the boss about giving you the day off today.
L: thank you. I can't imagine getting much done today. I'm just too exhausted!
Z: no problem. Did you bring any gifts back for your department?
L: no, should I have?
