a girl

A girl asks her friend to pass on to her house and take dinner with her parents. This is an important event, the girl tells her boyfriend that after dinner he wants to go to him and "do" for the first time. Of course, the boy is ecstatic, but he never had sex before, so it goes to pharmacy to get her some birth control methods. The pharmacist in charge of it for an hour, explaining in detail about sex. In the end, he asked how many condoms they want to buy: a 3-pack, each one 10 or 20. The boy insists on taking on the 20, because I think it will be very busy, being the first time.
Friday night the boy goes to girl's parents house and is greeted by his girlfriend at the door. The boy goes inside and is taken to the dinner table where the girl's parents and where they were. Boy proposes to immediately say prayer and bows his head.
One minute passes and the boy is still deep in prayer, head bowed. 10 mins go by and still not see any movement from the boy. Finally, after 20 minutes with his head bowed, his girlfriend and whispered close to her friend:
- I thought you were not so religious person.
The boy returned and whispered:
- No I do not think your father is a pharmacist.
