Elijah: Welcome to all the participants of our sailing course. I will be your instructor. We meet on Monday, 6 p.m. in room 12. 
Luis: Hello! Do I need to wear a specific type of clothes? I'll be coming straight from work, so I'd like to know beforehand if I need to pack something to change into.
Elijah: Hello, Luis. The first lesson will be purely theoretical, so you don't need any special gear.
Abel: Will it be okay if I bring my son with me? I've got no one to leave him with. He's six y.o. and he can be quiet when told to behave.
Elijah: Of course.
Abel: Thank you!
Elijah is an instructor of the sailing course. The meeting with participants is on Monday, 6 p.m. in room 12. Luis and Abel ask him about organisational matters.
