If you're hoping to convince your strict parents to get a pet, there are a few things you can do to make your case. First, try to find out what their objection is to having a pet. It may be that they're worried about the mess or the extra work involved in taking care of an animal. Once you know their main concern, you can address it directly. For instance, if they're worried about the mess, offer to help with cleaning up after the pet. Or if they're concerned about the extra work involved in taking care of an animal, volunteer to take on some of the responsibility yourself.
In addition, try to find out what kind of animal they might be open to considering as a pet. If they have any allergies or other specific preferences, take that into account when making your pitch. And finally, be prepared to answer any questions they may have about how you'll care for the pet and what kind of financial commitment you're willing to make. With a little preparation and patience, you may just be able to convince your strict parents to let you bring home a new furry friend!
