Diving goggles are not allowed in the swimming pool because they are designed for use in deep water and can obstruct peripheral vision, increasing the risk of collisions with other swimmers. Additionally, diving goggles are not necessary for swimming laps or recreational swimming in a pool with clear water. The use of diving goggles in a swimming pool can also create a safety hazard if the wearer dives into shallow water thinking it is deeper than it actually is. **

Using a diving mask instead of swimming goggles can provide a wider field of vision and better visibility underwater. Diving masks are designed to create a watertight seal around the eyes and nose, preventing water from entering. They also typically have a nose pocket for equalizing pressure while diving. However, diving masks may be bulkier and less streamlined than swimming goggles, which could affect comfort and performance while swimming laps. **

It ultimately depends on the individual's maturity level, life experiences, and personal beliefs. Age alone is not a determining factor in how one perceives another person's level of maturity. **

It is also important for the 20-year-old to consider the potential power dynamics at play and to ensure that the friendship is based on mutual respect and understanding. **

Some 17-year-olds may find 15-year-olds childish, while others may not. It ultimately depends on the individuals and their maturity levels.
